Abstract:

The issues discussed in this paper provide for further development of studies in the sphere of imaging spectroscopy and laser vision. In terms of forming the information fields (radiation fields), the electro-optical systems are subdivided into the passive and active ones. Passive electro-optical systems use the information fields formed by natural radiation sources, whereas the active ones suggest using artificial sources. Comparative analysis of mathematical and physical issues of designing the electro-optical systems with dynamic spectral processing of optical radiation of the passive and active types has been performed. It has been shown that the controlled dynamic spectral processing of optical radiation can be implemented within the passive and active electro-optical systems on the basis of the same algorithm that represents operation of the optical processor performing the mathematical operation of dot product. The authors have developed the block diagram of an active electro-optical system with dynamic spectral processing. The algorithm for optimal detection of optical signals has been developed using basics of the signal detection theory. Mathematical modeling of target detection against an inhomogeneous background has been performed. It has been shown that the optimal dynamic spectral processing of optical radiation in active electro-optical system enables to separate the desired optical signal by suppressing the background signal.

Abstract:

Human beings obtain big amount of information from the external world through their visual system. Automated system such as robot must provide the visual functions for their flexible operations in 3-D circumstances. In order to realize the visual function artificially, we would be better to learn from the human visual mechanism. Optical illusions would be a pure reflection of the human visual mechanism; they can be used for investigating human visual mechanism. New types of optical illusion with binocular viewing are introduced and investigated.

Abstract:

Despite the skill and determination of electro-optical system designers, the images acquired using their best designs often suffer from blur and noise. The aim of an “image enhancer” such as myself is to improve these poor images, usually by digital means, such that they better resemble the true, “optical object,” input to the system. This problem is notoriously “ill-posed,” i.e. any direct approach at inversion of the image data suffers strongly from the presence of even a small amount of noise in the data. In fact, the fluctuations engendered in neighboring output values tend to be strongly negative-correlated, so that the output spatially oscillates up and down, with large amplitude, about the true object. What can be done about this situation? As we shall see, various concepts taken from statistical communication theory have proven to be of real use in attacking this problem. We offer below a brief summary of these concepts.

Abstract:

Neutral atoms offer a promising platform for single- and many-body quantum control, as required for quantum information processing. This includes excellent isolation from the decohering influence of the environment, and the existence of well developed techniques for atom trapping and coherent manipulation. We present a review of our work to implement quantum control and measurement for ultra-cold atoms in far-off-resonance optical lattice traps. In recent experiments we have demonstrated coherent behavior of mesoscopic atomic spinor wavepackets in optical double-well potentials, and carried out quantum state tomography to reconstruct the full density matrix for the atomic spin degrees of freedom. This model system shares a number of important features with proposals to implement quantum logic and quantum computing in optical lattices. We present a theoretical analysis of a protocol for universal quantum logic via single qubit operations and an entangling gate based on electric dipole-dipole interactions. Detailed calculations including the full atomic hyperfine structure suggests that high-fidelity quantum gates are possible under realistic experimental conditions.

Abstract:

Spatiotemporal information processing within the human brain is done by a joint task of neurons and synapses with direct optical inputs. Therefore, to mimic this neurofunction using photonic devices could be an essential step to design future artificial visual recognition and memory storage systems. Herein, we proposed and developed a proof-of-principle two-terminal device that exhibits key features of neuron (integration, leaky, and relaxation) and synapse (short- and long-term memory) together in response with direct optical input stimuli. Importantly, these devices with processing and memory features, are further effectively integrated to build an artificial neural network, which are enabled to do neuromorphic spatiotemporal image sensing. Our approach provides a simple but effective route to implement for an artificial visual recognition system, which also has applications in edge computing and the internet of things.

Abstract:

Understanding the mechanisms by which sensory neurons encode and decode information remains an important goal in neuroscience. We quantified the performance of optimal linear and nonlinear encoding models in a well-characterized sensory system: the electric sense of weakly electric fish. We show that linear encoding models generally perform better under spatially localized stimulation than under spatially diffuse stimulation. Through pharmacological blockade of feedback input and spatial saturation of the receptive field center, we show that there is significantly less synaptic noise under spatially diffuse stimuli as compared with spatially localized stimuli. Modeling results suggest that pyramidal cells nonlinearly encode sensory information through shunting in their dendrites and clarify the influence of synaptic noise on the performance of linear encoding models. Finally, we used information theory to quantify the performance of linear decoders. While the optimal linear decoder for spatially localized stimuli could capture 60% of the information in pyramidal cell spike trains, the optimal linear decoder for spatially diffuse stimuli could only capture 40% of the information. These results show that nonlinear decoders are necessary to fully access information in pyramidal cell spike trains, and we discuss potential mechanisms by which higher-order neurons could decode this information.

Abstract:

Spin-bearing molecules are promising building blocks for quantum technologies as they can be chemically tuned, assembled into scalable arrays, and readily incorporated into diverse device architectures. In molecular systems, optically addressing ground-state spins would enable a wide range of applications in quantum information science, as has been demonstrated for solid-state defects. However, this important functionality has remained elusive for molecules. Here, we demonstrate such optical addressability in a series of synthesized organometallic, chromium(IV) molecules. These compounds display a ground-state spin that can be initialized and read out using light and coherently manipulated with microwaves. In addition, through atomistic modification of the molecular structure, we vary the spin and optical properties of these compounds, indicating promise for designer quantum systems synthesized from the bottom-up.

Abstract:

In electronic processors, heat dissipation and interconnection delay are serious design and performance limiting factors. Why then consider photonic components where both the energy and size of the photon are large (˜1 eV and ˜1 μm, respectively) and the required nonlinear interactions between electric or magnetic fields and photons for switching or modulation are small? There are several answers to this question. First, the wide bandwidth of optical communications systems is taxing the current capabilities of electronic switching technologies. Even a slow optical switch can switch a very wide bandwidth optical signal from one fiber to another. External optical modulators will likely be required in ultrawide bandwidth communications because of basic limitations on direct modulation of lasers. Because of the weak electromagnetic interaction and low dispersion, optical interconnection of electronic circuits offers considerable advantages in high speed computer architectures. Some of these applications would appear to be relatively near term since they build on current capabilities of optical communication.Longer term and more speculative are applications of photonics to computation and image processing — areas where electronics technology is already mature. Current research can be divided into two groups — ultrafast processing and parallel processing. The first group concentrates on processing with ultra-fast optical pulses. Optical pulses as short as 6 fs — orders of magnitude shorter than any electronic pulses — have been generated in the research laboratory. High processing rates are achievable by serial processing of high repetition rate ultrashort pulses. This approach requires ultrafast switches, which in turn requires materials with ultrafast nonlinear optical response time. Indeed, the shortest electrical signals are now measured by optical sampling techniques.

Abstract:

The article considers the fundamentals of the information reproduction systems formation in the optoelectronic element base for information logistics systems. The use of optoelectronic elements for information processing has been considered, namely discrete optoelectronic digital systems, analog systems, optical memory systems, optical systems of input-output of information in computers, systems based on fiber devices of neuristor type. It is emphasized that modern logistics is impossible without the active use of information technology. The functions of information support of managerial influences can be performed by information technologies used today in logistics. To perform the tasks of financial flow management, these technologies can be supplemented by modules of eye-processing of the information. Logic-clock quantron automatic devices based on optocouplers are suitable for creating parallel information operating environments, which is a universal means of converting and presenting information. This approach leads to the creation of matrix-type devices that are able not only to receive information but also to process it. One of the promising areas of use of optoelectronic matrix systems is the creation of flat operating screens for parallel reception and display of information. The paper presents the classification of operating screens according to such features as: the principle of displaying information, the type of input information, the type of output information, the method of image formation, the number of consumers of the information. The analysis of electric circuit diagram of modern LED matrix video screens, in particular of a typesetting-modular design has been presented. A comparison of the forms of organization of matrix video screens is made, and it is emphasized that the most economical in terms of the number of memory trigger elements per one LED of the display cell is a video information system based on the structure of the third group video screen. The structure of the video information system is optimized according to the criterion of optimality – the maximum image quality on the matrix screen and the minimum screen complexity, which is determined by the circuit features of the microelectronic circuits.

Abstract:

Nonlinear optics has been of increased interest for all-optical signal, data and image processing in high speed photonic networks. The application of multi-valued (nonbinary) digital signals can provide considerable relief in transmission, storage and processing of a large amount of information in digital signal processing. Here, we propose the design of an all-optical system for some basic tri-state logic operations (trinary OR, trinary AND, trinary XOR, Inverter, Truth detector, False detector) which exploits the polarization properties of light. Nonlinear material based optical switch can play an important role. Tri-state logic can play a significant role towards carry and borrow free arithmetic operations. The principles and possibilities of the design of nonlinear material based tri-state logic circuits are proposed and described.

Abstract:

We study limits for the detection and estimation of weak sinusoidal signals in the primary part of the mammalian auditory system using a stochastic Fitzhugh-Nagumo model and an action-recovery model for synaptic depression. Our overall model covers the chain from a hair cell to a point just after the synaptic connection with a cell in the cochlear nucleus. The information processing performance of the system is evaluated using so-called φ-divergences from statistics that quantify “dissimilarity” between probability measures and are intimately related to a number of fundamental limits in statistics and information theory (IT). We show that there exists a set of parameters that can optimize several important φ-divergences simultaneously and that this set corresponds to a constant quiescent firing rate (QFR) of the spiral ganglion neuron. The optimal value of the QFR is frequency dependent but is essentially independent of the amplitude of the signal (for small amplitudes). Consequently, optimal processing according to several standard IT criteria can be accomplished for this model if and only if the parameters are “tuned” to values that correspond to one and the same QFR. This offers a new explanation for the QFR and can provide new insight into the role played by several other parameters of the peripheral auditory system.

Abstract:

The accuracy of the coordinates of ground objects measured using optical instruments by unmanned aerial vehicles depends on many factors including: errors in measuring the angular coordinates of the optical system, the distance to the object, the presence of heterogeneous terrain, etc. Traditional use of optoelectronic systems functioning based on inertial sensors demonstrated their flaws, such as low accuracy at ground objects positioning for target designation to unmanned aerial vehicles due to declination angle and azimuth determination inaccuracy. In this work, a variant of optimizing the algorithm for analyzing and processing information in an optoelectronic system for determining the coordinates of ground objects from an unmanned aerial vehicle is presented. An algorithm and a method for determining geographical coordinates based on an electronic height matrix have been developed. An increase in the accuracy of calculating the coordinates of an object was achieved by minimizing the error of measuring the declination angle, azimuth on a ground object and inclined range. A description of a full-scale experiment with a car on the ground is given. Its essence was that according to several freeze frames obtained by the optoelectronic system of an unmanned aerial vehicle at a considerable distance with a large inclined range, the geographical coordinates of the car were determined in two ways (traditional and developed). With the help of the method proposed by the authors, the accuracy of determining coordinates has been increased several times. The developed algorithm and method for information processing make it possible to create a variety of hardware and software solutions for guidance and target designation systems of unmanned aerial vehicles.

Abstract:

A all-fiber perimeter alarm system is designed which is composed of the optical Fiber Sensor Module(FSM) laid along the perimeter and Security Information Control Center(SICC) (including display terminals-the large screen display, the terminal of personnel operation, the system control host, etc.) and optical fiber fence (or sensor board). It uses optical fiber (cable) as the sensing and transmission device, through directly contacting with optical fiber (cable) or through the carrying material, passing various disturbances to the fiber (cable), carrying continuous real-time monitoring and collecting disturbance data. Through the back-end analysis, processing and intelligent identification, it can determine the different types of external disturbances. The system can automatically obtain the real-time alarm information that the optical cable generates and process these warning messages according to predefined business logic, then generate sound and light warning prompt and provide several functions of statistics, query on the warning message.

Abstract:

Abstract We use optimal control theory to show that for a closed Λ-system where the excited intermediate level decays to the lower levels with a common large rate, the optimal scheme for population transfer between the lower levels is actually optical pumping. In order to obtain this result we exploit the large decay rate to eliminate adiabatically the weakly coupled excited state, then perform a transformation to the basis comprised of the dark and bright states, and finally apply optimal control to this transformed system. Subsequently, we confirm the optimality of the optical pumping scheme for the original closed Λ-system using numerical optimal control. We also demonstrate numerically that optical pumping remains optimal when the decay rate to the target state is larger than that to the initial state or the two rates are not very different from each other. The present work is expected to find application in various tasks of quantum information processing, where such systems are encountered.

We study distinguishing information in the context of quantum interference involving more than one parametric downconversion (PDC) source and in the context of generating polarization-entangled photon pairs based on PDC. We arrive at specific design criteria for two-photon sources so that when used as part of complex optical systems, such as photon-based quantum information processing schemes, distinguishing information between the photons is eliminated guaranteeing high visibility interference. We propose practical techniques which lead to suitably engineered two-photon states that can be realistically implemented with available technology. Finally, we study an implementation of the nonlinear-sign shift (NS) logic gate with PDC sources and show the effect of distinguishing information on the performance of the gate.

Abstract:

The article discusses a method for increasing the contrast of images in an optoelectronic system based on active dynamic spectral matched filtering. The principles of constructing active optoelectronic systems with matched filtering are based on the fact that the optical system uses a set of amplitude-controlled radiation sources operating in different parts of the spectral range as emitting sources. It is essential that the energy composition of the light emission control signals is formed on the basis of a priori information about the characteristics of the target and the background, so as to reduce the value of the spectral components of the optical signal reflected from the surface belongs to the background and with minimal attenuation of the signal intensity belonging to the object. The method assumes the presence of a set of a priori information about the spectral characteristics of the background and the object to form the instrumental function for controlling the amplitude of emitting sources. The analysis of the mathematical and physical aspects of systems with dynamic spectral processing of active type optical emitting is made. It is shown that an active optoelectronic system with dynamic spectral processing can be considered as an analog processor for calculating the dot product of a vector by a vector. One of the factors is the reflection coefficient from a surface with a priori known characteristics, and the second is a dimmable multispectral signal. A block diagram of an optoelectronic system with dynamic spectral processing of optical emitting with active formation of the information field in order to increase the contrast of the object image has been developed. The goal of the article is to develop the mathematical and physical foundations for constructing an active optoelectronic system with dynamic spectral processing of optical emitting in order to increase the image contrast.

Abstract:

The possibility of using the fundamentals of system analysis when choosing the optimal information processing strategy in the design of complex information systems with the aim of obtaining a complete and objective assessment of information resources, implemented in the interest of analyzing the technical characteristics of integrated information processing tools of complex automated systems, is considered. Information risk analysis was carried out, i.e. the process of integrated assessment of information processing in an automated system with the transition to quantitative or qualitative indicators. In addition, each indicator represents the probable damage, which depends on the information processing in the system. The process of identifying and reducing risks that can affect the information system is understood as the process of risk management. The results of the analysis are used in the selection of information processing facilities and in evaluating the effectiveness of existing and projected subsystems.

Abstract:

During the control of technological processes of manufacturing various parts, which are required to increase the accuracy of processing, it is necessary to adhere to the systematic measurement of their geometric dimensions, tolerances, compliance with the shape and location of the surfaces of the parts. To date, this type of non-destructive testing is carried out using special optical systems and allows you to study different products, regardless of their type, design features and structure of the materials from which they are made. That is, the visual-optical method of measurement is one of the most important methods of non-destructive testing in production. In the article the authors shared practical experience in the selection and optimal use of 3D video measuring system with limited resources. The choice of manufacturer and model (type) of video measuring system was made depending on the complexity of the measurement tasks. First of all, the error of measurement results was evaluated, which was determined by technical indicators and the composition of software functionality. For control in the manufacture of high-precision mechanical parts, the basic requirements for technical parameters and software of the video measuring system are defined. Emphasis is placed on the economic effect by reducing the time of measurement of linear dimensions and angles in the plane of the controlled parts, while using high-quality functionality of video processing, which significantly reduces the likelihood of operator error. The choice between manual and automated measurement systems is justified: the main factors are the capacity and the required amount of measurements. Evaluated as a positive ability to save information files in Exel, Word, and SPC for statistical processing of information to improve the quality of parts. Features of video measuring systems concerning: implementation of innovative metrological solutions - multisensory metrology, namely - inclusion in the program of measurements of optical, laser and contact research; Reverse Engineering of previous versions of parts for which drawings have already been lost and CAD models are not available.

Abstract:

The review presents the results of a long-term collaboration of three research teams from Surgut, Tula and Moscow, which carried out the development of innovative methods of analyzing, processing and information management to ensure the adoption of optimal solutions and to improve the efficiency of the health system. Research teams have created an intelligent system to work with semi-structured data arrays. Creating the theory of chaos and self-organization of systems, based on compartment and cluster approach, is justified. It was shown the possibility of controlling the functional systems of the human body by methods of regenerative medi-cine. The authors have developed a system of databases formation and intelligent decision-making and imple-mentation, proving the versatility of neural network approach and adaptation it to the information processing, obtained in the course of medical research. The vastness of the received information has led to the brevity of presentation with a sufficient number of references to the realized works.

Abstract:

The process of dynamic spectral processing of optical radiation in the active electro-optical system that provides enhancement of the contrast of the image target has been experimentally researched. A routine of experiment and a diagram of an experimental setup have been developed. The sources of optical radiation in the transmitting part of the active electro-optical system were three semiconductor lasers operating in the ranges of the red, green, and blue spectral regions. Absorption optical filters were used in the experiment as the elements simulating the spectral properties of the reflecting surfaces of the target and the background. To enhance the contrast of the target image, the spectral composition of the laser radiation is formed to provide maximum suppression of the background signal with minimum attenuation of the optical signal of the object. When forming the spectral density of the laser radiation intensity, a priori information about the spectral characteristics of the target and the background has been used. The results obtained in the course of the experiment confirm the possibility to separate the target signal from the background interferences due to using the dynamic spectral processing of optical radiation in the active electro-optical system.

Abstract:

The optimization of the methods for the formation of the spatial-energy distribution of the probing radiation power and the processing the receiving signal by the locating laser information-measuring systems (LIMS), taking into account the spatial-temporal structure, is carried out, and the analysis of the existing methods of their processing is carried out too. An assessment of the integral criteria for the LIMS functioning when operating in conditions of interference has been made. The calculation of the parameters of the LIMS main links was carried out, taking into account the correlation between the resolution of the optical system and the capabilities of object detection, recognition and classification. A method was developed for the formation of the probing radiation density distribution and the receiving signal processing, taking into account its space-time structure, which made it possible to determine the optimal duration of the laser probe pulse. The determined duration makes it possible to eliminate errors in measuring the parameters of an object's movement under the influence of a combination of destabilizing factors and a lack of signal processing time, which will ensure the accuracy of the target detection and recognition.

Abstract:

The Société de Transport de la Communauté Urbaine de Montréal (STCUM; Montreal Urban Community Transit Corporation) has recently undertaken the task of computerizing its phone information center, called AUT-OBUS. AUT-OBUS provides callers with optimal route choices within the STCUM transit network. An original system based on geographic and operations data bases combined with interactive path calculation and data processing software has already been implemented. A special geographic information system was developed to process the origins and destinations on the basis of the client's specifications. Multiple forms of spatial referencing are provided: street addresses, trip generators and attractors, monuments, special activities, street intersections, transit references (subway and rail stations, bus routes, terminals, etc.). The best path calculation is carried out by using interactively calibrated impedance functions (walking, in-vehicle, waiting, transfers, fares, and mode restriction). An added challenge was the necessary consideration of the network geometry, commercial speed, day type, trip time, and headway and the validation of the computed paths with existing schedules. For a transit network the size of Montreal's, consisting of 16,000 bus stops, 230 bus routes, and a pedestrian network of 80,000 links and 28,000 nodes, the calculation of the optimal path for a given origin–destination pair is less than 2 sec with a typical personal computer with a Pentium processor.
