Abstract:
We present a free-space optical displacement sensor for measuring geological slip event displacements within a laboratory setting. This sensor utilizes a fiberized Mach-Zehnder based optical heterodyne system coupled with a digital phase lock loop, providing a large dynamic range (multiple centimeters), high displacement resolution (with an amplitude spectral density of [Formula: see text] m/[Formula: see text] for frequencies above 100 Hz), and high velocity tracking capabilities (up to 4.96 m/s). This displacement sensor is used to increase the displacement and the time sensitivity for measuring laboratory-scale earthquakes induced in geological samples by using a triaxial compression apparatus. The sensor architecture provides an improved displacement and time resolution for the millisecond-duration slip events, at high containment and loading pressure and high temperatures. Alternatively, the sensor implementation can be used for other non-contact displacement readouts that required high velocity tracking with low noise and large dynamic range sensing. We use 13 high-velocity slip events in Fontainebleau sandstone to show the large dynamic range displacement tracking ability and displacement amplitude spectral densities to demonstrate the optical readout’s unique sensing capabilities.

Abstract:
With the advantages of high resolution, structural simplicity, reliability, compact size, and high sensitivity, inductive sensors have been widely used in nanopositioning systems. However, the measuring range of traditional inductive sensors are usually limited to 0.2 mm. A novel analysis and design methodology of the miniaturized inductive sensor with large measuring range and nanoscale resolution is proposed. Firstly, an accurate leakage inductance model is established. Secondly, a design rule of armature size is proposed by considering the fringing effect. Then, the error terms introduced by the measurement circuit of differential inductive sensors are analyzed and the corresponding error suppression methods are illustrated. Moreover, A design rule of selecting the optimal excitation frequency is proposed to meet the requirements of high Q value and high bandwidth, and to minimize the impact of core loss resistance on the performance of the sensor. Validated by the experiments, the proposed analysis and design method can effectively guide the design of the miniaturized inductive sensor with nanoscale resolution in the measuring range of ±0.5 mm. The overall size of the fabricated sensor prototypes is less than 6 mm × 6 mm × 3 mm. Combined with large range, high resolution and ideal miniaturization, this inductive sensor can be well suitable for compact and large stroke nanopositioning systems.

Abstract:
The low-resolution photoelectric position sensor is used, that is, Hall position sensor replaces the traditional photoelectric encoder and other high-resolution position sensors to monitor the rotor position. However, because the three-phase Hall position sensor can only output six position signals, a hardware circuit design of low-resolution position sensor monitoring rotor position signal is proposed. Meanwhile, nanotechnology has been introduced in the study of micro drive of battery electric vehicle (BEV). BEV driver has some disadvantages such as hysteresis, creep and nonlinearity, which seriously affects its application in nano environment. A nano displacement sensor is designed for the characteristics of BEV driver. The nonlinear problem of micro driver is solved through the closed-loop control of position feedback. In the test, through the verification of rotor position and current waveform, it can be proved that the method based on photoelectric position sensor and rotor position signal monitoring can ensure the low deviation of rotor position calculation and correct output signal of three-phase photoelectric position sensor. The decoupling performance of vector control is verified by 3/2 transformation. In the displacement detection of micro driver, the designed nano displacement sensor has higher resolution and its performance is better than that of the previous three generations of displacement sensors.

Abstract:
Abstract Optical displacement metrology is important in nanotechnology and used to identify positions and displacements of nanodevices. Although several methods have been proposed, a sensor with ultracompact size, angstrom-scale resolution, and large measurement range is still lacking. We propose an optical displacement sensor with wavelength modulation that can demonstrate subwavelength footprint and angstrom-level resolution with large measurement range in this study. The proposed sensor consists of two optical slot antennas. Surface plasmon polaritons (SPPs) are launched at antennas and interfere when a tightly focused broadband light source illuminates the sensor. Spectrum of output SPPs presents a dip, which depends on the position of focal spot of incident light and is used to extract displacement. A maximum resolution of 0.734 nm was obtained. Furthermore, we used interference fringe of two broadband beams as light source and the measurement range of the sensor is not limited by the size of the tightly focused light source while maintaining high resolution. The method utilizes a new mechanism of wavelength modulation to overcome the trade-off between the high resolution and large measurement range, and achieve a variety of potential applications for nanometrology in the future.

Abstract:
The precision positioning device becomes significant requirement in scientific instruments used for the applications of nanotechnology for a few decades. To achieve the high resolution positioning, the sensing methods of displacement sensor become more important in positioning device. In this paper, a novel method is presented for measuring both in-plane/out-plane displacements with the single heterodyne grating interferometry (HGI). We demonstrated the 1D, 2D, and 3D measurement results respectively and the smallest displacement can be detected was better than 6 pm. Furthermore, the nanometer resolution can be ensured within 20 µm displacement. Hence, the in-plane/out-plane measurements with single apparatus can be realized by our method and might be a displacement sensor using in the motorized stage with suitable opto-mechanics structure minimization.

Abstract:
L’objectif de la thèse est de réaliser un système de convoyage flexible permettant de déplacer des micro-objets. Ce système pourra être amené à être intégré dans une micro-usine ce qui nécessite une forte reconfigurabilité et une faible consommation d’énergie. Ces deux critères ont donc été considérés lors de la conception du système de convoyage. Ce dernier est basé sur un actionneur planaire électromagnétique, développé au sein du laboratoire Roberval, et sur une surface intelligente composée de 5 × 5 cellules élémentaires permettant chacune de déplacer la partie mobile dans les deux directions du plan et des rotations autour de l'axe perpendiculaire au plan. Un modèle analytique de l’actionneur a été développé afin de calculer les efforts électromagnétiques ainsi que le déplacement de la partie mobile. Ce modèle a été utilisé lors de la phase de conception du système de convoyage. Un prototype expérimental a ensuite été fabriqué et testé ce qui a permis de valider le principe de fonctionnement proposé. Des tests expérimentaux ont montré la possibilité de réaliser des déplacements de grande étendue dans les deux directions du plan. De multiples tests expérimentaux (pilotage en boucle ouverte, caractérisation des performances telles que rectitude de déplacement, répétabilité de positionnement, charge déplaçable, …) a été réalisée afin de qualifier les performances du système de convoyage. Les points sur la réalisation : - Une modélisation statique sous RADIA a été développée afin de concevoir la surface intelligente notamment la zone de transition entre deux cellules voisines. Une modélisation dynamique réalisée sous MATLAB a permis de simuler le comportement d’un moteur en boucle ouverte et en boucle fermée. - Un prototype de surface intelligente, composé d’un circuit imprimé multicouches (4 couches) de dimensions 130 mm x 130 mm, a été conçu sous EAGLE software. L’influence de la distance entre les deux premières couches a été étudiée à l’aide des modèles développés afin d'assurer un déplacement uniforme dans les deux directions. - Un test expérimental avec LABVIEW interface d'une cellule élémentaire de la surface intelligente avec une partie mobile composée de deux moteurs magnétiques orthogonaux a été réalisé et a permis de valider le fonctionnement du système de convoyage dans les deux directions du plan. - Une autre série de tests avec LABVIEW interface a été réalisée afin de valider expérimentalement le déplacement de la partie mobile avec la surface intelligente au niveau des zones de transition entre les cellules élémentaires. Ces tests expérimentaux ont montré des déplacements de grande étendue dans les deux directions du plan et de rotation autour de l'axe perpendiculaire au plan. Des déplacements de grande étendue et des rotations de la partie mobile ont été mesurés à l’aide d’une méthode de traitement d'image réalisée sous MATLAB. - Parallèlement, on a étudié un capteur à déplacement optique à haute résolution qui peut être intégré dans le convoyeur. Un algorithme robuste pour le traitement du signal de capteur à fibres optiques à haute résolution pour mesurer de déplacement est développé. Dans cet algorithme, la position optimale de la partie mobile est déterminée pour obtenir un basculement sans arrêt entre les sondes et l'algorithme est implémenté sous MATLAB et validée par la mise en œuvre des signaux expérimentaux. Ces travaux de thèse ont été publiés dans une revue internationale (Computers in Industry (COMIND)) et présentés dans des congrès internationaux (IEEE Sensors, REM Mechatronics, AIM, IWMF) pendant les années 2011 à 2016
The aim of the thesis is to provide a flexible conveyor system for moving micro-objects. The system may need to be integrated into a micro-factory which requires high reconfigurability and low power consumption. These two criteria have been considered in the design of the conveyor system. The conveyor is based on a planar electromagnetic actuator developed in the Laboratoire Roberval of the UTC, and on smart surface composed of 5 x 5 unit cells; each ceii moves th movable part in the two directions of the plane. An analytical model of the actuator has been developed in order to calculate the electromagnetic forces and the displacement of the mobile part. This modei has been used during the design phase of the conveying system. An experimental prototype is then manufactured and tested which has validated the proposed principle of operation. Experimental tests have shown the ability to perform wide area displacement in both directions of the plane. Numerous experimental tests (control in open loop and closed loop performance characterization as straightness of movement, position repeatability, coupled- decoupled analysis...) have been done to qualify the performance of the conveyor system. Experiments for rotations about the axis perpendicular to the olane have also been performed successfully. Work synthesis: - Static modeling under RADIA was developed in order to design the conveyor surface especially for the transitio zone between two neighboring cells. A dynamic modeling under MATLAB allowed to simulate the behavior of single axis motor in open loop and closed loop control. - A conveyor surface prototype, consisting of a multilayer printed circuit board (4 layers) of dimensions 130 mm x 130 mm, was designed under EAGLE software. The influence of the distance between the first two layers was studied using the developed models to ensure uniform displacement in both the directions. - The experimental tests (with LABVIEW interface) of an elementary cell of the intelligent surface with a moving part composed of two orthogonal magnetic motors has been carried out that allowed to validate the operation of the conveying system in both directions of the plane. - Another series of tests with LABVIEW interface were carried out in order to validate experimentally the displacement of the mobile part with the smart surface at the transition zones between the elementary cells. - These experimental tests showed displacements of great extent in the two directions of the plane and of rotation about the axis perpendicular to the plane. - Long displacements and rotations of the moving part were measured using image processing algorithm developed in MATLAB. - At the same time, a high resolution fiber optic displacement sensor was studied that can be integrated into the conveyor surface locally for the precise positioning. A robust signal processing algorithm for high resolution displacement measurement was developed. In this algorithm, - The optimum position of the movable part is determined in order to obtain a continuous switching betwee the two fiber optic probes ; - The usable parts of the signals obtained from two probes were then filtered to measure the displacement using interpolation method ; The algorithm is implemented under MATLAB and validated by the implementation of the experimental signals. The work have been published in an international journal (Computers in Industry (COMIND)) and presented at international congresses (IEEE Sensors, REM Mechatronics, AIM, IWMF) during the years 2011 to 2016

Abstract:
As specialized materials are developed for various applications, it becomes desirable to test them under adverse conditions, such as at elevated temperatures and in harsh environments. It is increasingly important that sensors be developed to meet the growing needs of research and industry. The ability of sapphire to withstand elevated temperatures and many chemically harsh environments has long been recognized. However, currently available sapphire fiber possesses poor optical quality and is not available with a cladding. It has found use in a variety of temperature sensors, but the investigation of sapphire-based strain and displacement sensors has been limited.

The primary development of a white-light Michelson interferometer that utilizes a sapphire fiber sensing head is presented in this thesis. Development includes efforts to combat the poor optical quality of the sapphire fiber, minimize polarization mode fading, and preferentially excite the fundamental mode of the sapphire fiber. This thesis demonstrates the feasibility of fabricating a Michelson white-light interferometer capable of measuring displacements in environments ranging from room temperature to 800 degrees Celsius. The sensor developed in this work is capable of measuring displacements exceeding 6.4 millimeters at room temperature, and exceeding 1 millimeter at 800 degrees Celsius.

This thesis also presents the application of this sensor to the alignment of a sapphire-fiber based Fabry-Perot sensor. This technique allows the Fabry-Perot sensor to be aligned so that usable fringes are always obtained. Alignment of the sapphire-fiber based Fabry-Perot sensors has been considered prohibitively difficult.

Abstract:
The aim of this research is to investigate a novel Multiple-Input-Multiple-Output (MIMO) sensor system for automotive applications. Compared to traditional phased arrays, a MIMO array can achieve the same fine angular resolution, but with a drastically less amount of sensor elements. For example, a MIMO array of 10 elements can deliver the same resolution as a phased array of 25 elements. The other highlight of this technology is that it can operate at short ranges, which is physically impossible with a phased array. Therefore, a MIMO system can potentially provide very high angular resolutions at short ranges. These properties make such a system attractive for a number of automotive applications, including parking aids, short-range cruise control, speed-over-ground estimation, pedestrian detection etc. Research started with the verification of application of conventional MIMO techniques for radar context. MIMO techniques were tested with the existing RF equipment in laboratory environment. Beamforming capabilities were verified, range and angular resolutions were compared to equivalent phased arrays and multiple-target resolving capabilities were confirmed. Nearfield focusing algorithms for MIMO arrays were developed and verified via experiments in the anechoic chamber with the same equipment. A technology demonstrator based on ultrasonic equipment was built and then tested in an anechoic chamber and the findings were compared to computed performance parameters. Further performance optimisations via aperiodic MIMO configurations were explored via use of heuristic optimisation algorithms. An optimised configuration then was tested in anechoic chamber and its performance was confirmed in experimentally. Finally using radio equipment again, an initial study on MTI applications was done. Platform motion compensation methods were developed and tested in order to make up for vehicular motion and to compensate for its possible effects. Both stationary platforms and a moving platform was used to experimentally confirm the MTI capabilities on both in an indoor setup and an outdoor setup.

Abstract:
This dissertation presents the design and development of a high precision driver for an eddy current displacement sensor. The project was initiated to supplement the development of a low-cost PCB eddy current displacement sensor for active magnetic bearings (AMBs). The sensor driver will be implemented in AMB systems that will be used in various high-speed applications. The sensor driver is required to drive an eddy current PCB sensor, condition the output signals from the sensor, and send the conditioned position signals to an embedded digital controller. Circuit board design and development therefore constitute the main focus of this project. Research on the defining concepts of the project was imperative in gaining the necessary understanding of the project. AMB systems and the sensors used in these systems were investigated first. The eddycurrent type sensor used in this project, as well as the PCB sensor technology used were also researched. As analogue design constituted a main aspect of this project, the concepts of signal conditioning and sensor characteristics had to be comprehended. The sensor driver consists of several sub-systems, including a sensor excitation circuit to drive the sensor, a signal conditioning circuit to condition the output signals of the sensor, and a digital processing circuit for further processing of the position signals. A conceptual design was performed for each of these sub-systems, followed by a detail design, in which the conceptual designs of the sub-systems were realized. All the sub-systems were then integrated, and lastly evaluated. The evaluation of the sensor driver system included verification and validation of the system. The sensor driver design was verified, while the final sensor driver board was validated with regards to its specifications. Additional circuit characteristics such as signal-to-noise-ratio, sensitivity and resolution were also determined in order to characterize the sensor driver system. The overall outcome of the sensor driver project was successful, with all the characteristics of the sensor adhering to the requirements. It was determined that the sensor driver has a signal to noise ratio of 54 dB, a linearity of 9 %, a sensitivity of 26 .4 V/mm, and a resolution of 792.5 nm. Recommendations are made with regards to the sensor cables, heat distribution, and the low-pass filter on the field programmable gate array (FPGA). Future work will mainly focus on implementation of the sensor driver on a test bench and implementation of the linearization algorithm. Additional future work includes a study on EMC effects on the system and especially the cables, and further firmware enhancements of the sensor driver. These include input signal testing and temperature compensation. An investigation on the required excitation current for optimal sensor operation should also be done.

Abstract:
Being able to predict the evolution of plastic deformation at the microstructural scale is of paramount importance in the engineering of materials for advanced applications. However, this is not straightforward because of the multiscale nature of deformation heterogeneity, both in space and time . The present thesis combines four related studies in a coherent work, which is aimed to develop experimental methods for studying crystal plasticity at the micro and mesoscale. A novel methodology for gold remodelling is initially proposed and used to apply high-density speckle patterns on the surface of stainless steel specimens. The unique proprieties of the speckle pattern enabled plastic deformation mapping with submicron resolution using digital image correlation (HDIC). It was therefore possible to study the concomitant evolution of microbands and transgranular deformation bands in such alloy. High-resolution deformation mapping also enabled comparison with high-resolution electron backscatter diffraction (EBSD) observations. The only partial correspondence of results proved the limits of EBSD in characterizing plastic deformation. The cause of such limitation is later identified in the reduced sensitivity to lattice slip of the EBSD technique. Hence, a novel method of HDIC data analysis is proposed to separate the contributions of lattice slip and lattice rotation from the deformation mapping. The method is adopted to characterize plasticity in austenitic stainless steel and at the plastic deformation zone (PDZ) around a silicon particle embedded in a softer aluminum matrix. Results show that the proposed experimental methodology has the unique capability of providing a complete description of the micro and mesoscale mechanics of crystal plasticity. HDIC therefore emerges as a key technique in the development of accurate physical-based multiscale crystal plasticity models.

The U.S. Army Research Laboratory (ARL) is developing an onboard instrument and telemetry system to obtain measurements of the 30mm MK310 projectile's in-flight dynamics. The small size, high launch acceleration, and extremely high rates of this projectile create many design challenges. Particularly challenging is the high spin rate which can reach 1400 Hz at launch. The bandwidth required to continuously transmit solar data using the current method for such a rate would leave no room for data from other sensors. To solve this problem, a data compression scheme is implemented that retains the resolution of the solar sensor data while providing room in the telemetry frame for other measurements.

Abstract:
Optical fibre sensors have offered such unrivalled distributed sensing features that they continue to be successfully exploited in various industries for performing continuous measurements of the physical parameters, such as, temperature and strain. However, there arise certain conditions in engineering or materials manufacturing and characterisation environments, when the user seeks to extract the knowledge about a single physical parameter only, say strain, whilst the environment is also subject to temperature. This thesis explores techniques to offer solutions under such conditions by developing a high spatial resolution temperature compensated distributed strain sensor. The preliminary exploration involved exploiting the high spatial resolution Brillouin frequency based Brillouin optical correlation domain analysis technique in combination with the anti Stokes Raman intensity based optical time domain reflectometry technique. This work resulted in achieving a temperature compensated strain resolution of 46με with a spatial resolution of 24cms over a sensing length of 135m. Tackling the impact of modest pump depletion effects on the Raman backscattered signal, a beneficial normalisation protocol was identified. During discussions the possible limitation imposed by the weaker backscattered Raman signal towards achieving any better results on the strain and spatial resolution values, seemed to emerge. In order to enhance the performance of the sensor, anti Stokes Brillouin, which is a stronger back scattered signal, was exploited for the time domain reflectometry measurements. This resulted in 22με of temperature compensated strain resolution with a spatial resolution capability of 10cms. Although the combined performance of the Brillouin frequency in combination with Brillouin intensity proved better than the performance of the Brillouin frequency in combination with Raman intensity, but since the electronic detection system was changed together with pulse widths between the two techniques that it was unclear as to which combinatory technique was best suited for designing the sensor. It is with this view that a theoretical analysis on the performance of the R-OTDR and B-OTDR was carried under similar sensor parameters. B-OTDR is identified as a better technique compared to the R-OTDR towards providing high spatial resolution temperature compensation feature to the Brillouin frequency based distributed strain measurements. The exploration also gave an opportunity to experimentally study for the first time the impact of simultaneously varying temperature and strain on the four Brillouin coefficients. This study proved useful in identifying the corrections to the Brillouin coefficients in order to estimate the true value of strain and temperature in a temperature controlled variable strain environment. The thesis culminates with a summary of work, discussing the thresholds of various non linear effects together with means to improve the performance of the sensor. With the view of enhancing the sensor applicability, schemes of loss compensation are also discussed. In conclusion work for the future is highlighted.

Abstract:
Sub-micron accuracy and precision in measuring unconstrained, spatial motion is pivotal in science and engineering. It imposes stringent requirements on the accuracy, reliability, and invasiveness of sensing devices (including lasers, lidar sensors, or optical scales). While the capabilities of these devices have seen dramatic improvements in the last decades, the needs for sub-micron accuracy, low-invasive sensors greatly outpace the available solutions. The root cause of measurement difficulties is a conflict between the very nature of motion (simultaneous translations and rotations relative to a chosen reference base) and the fundamental requirement of measurement accuracy known as the Abbe principle. Small and accurate Microsystems Technology based inertial sensors (accelerometer and gyroscopes) can alleviate, or at least significantly mitigate, many of the current difficulties. If contained in small Inertial Measurement Units (IMU) and equipped with a wireless signal transmission, they can be placed on or very close to the objects whose motion is to be measured. Furthermore, as long as the IMU, its fixture, and some region of this object around the fixture can be considered as rigid, coordinate transformation rules facilitate converting signals measured by IMU into translations and rotations of any point in this rigid region. Consequently, a virtual 6-DOF sensor can be created. Its dimensions are infinitesimally small, and it can be “placed” anywhere within the above rigid region. In particular, it can be placed such that it is collinear with the displacements of the cutting tool or robot’s end effector, and satisfies the Abbe principle. We present a High Accuracy, Low-Invasive Displacement Sensor (HALIDS) for application in manufacturing and in engineering design. The sensor is capable of measuring simultaneously 6-degrees-of-freedom displacements of objects. Its short term resolution is down to 0.1 nanometer and accuracy better than 1 micron. The sensor can be built small, light and wireless. Results from experimental evaluation of two prototype versions are presented.

Abstract:
Autonomous vehicles (AVs) utilize multiple devices, like high-resolution cameras and radar sensors, to interpret the driving environment and achieve full autonomy. One of these instruments—the light detection and ranging (LiDAR) sensor—utilizes pulsed infrared (IR) light, typically at wavelengths of 905 nm or 1,550 nm, to calculate object distance and position. Exterior automotive paint covers an area larger than any other exterior material. Therefore, understanding how LiDAR wavelengths interact with vehicle coatings is extremely important for the safety of future automated driving technologies. Sensing technologies and materials are two different industries that have not directly interacted in the perception and system sense. With the new applications in the AV industry, multidisciplinary approaches need to be taken to ensure reliability and safety in the future. Unsettled Topics Concerning Coating Detection by LiDAR in Autonomous Vehicles provides a transversal view of different industry segments, from pigment and coating manufacturers to LiDAR components and vehicle system development and integration. The report includes a structured decomposition of the different variables and technologies involved.
