Abstract:
Spectral imagers divide scenes into quantitative and narrowband spectral channels. They have become important metrological tools in many areas of science, especially remote sensing. Here, we propose and experimentally demonstrate a snapshot spectral imager using a parallel optical processing paradigm based on arrays of metasystems. Our multi-aperture spectral imager weighs less than 20 mg and simultaneously acquires 20 image channels across the 795- to 980-nm spectral region. Each channel is formed by a metasurface-tuned filter and a metalens doublet. The doublets incorporate absorptive field stops, reducing cross-talk between image channels. We demonstrate our instrument’s capabilities with both still images and video. Narrowband filtering, necessary for the device’s operation, also mitigates chromatic aberration, a common problem in metasurface imagers. Similar instruments operating at visible wavelengths hold promise as compact, aberration-free color cameras. Parallel optical processing using metasystem arrays enables novel, compact instruments for scientific studies and consumer electronics.

Abstract:
Joint intrinsic and extrinsic calibration from a single snapshot is a common requirement in coastal monitoring practice. This work analyzes the influence of different aspects, such as the distribution of Ground Control Points (GCPs) or the image obliquity, on the quality of the calibration for two different mathematical models (one being a simplification of the other). The performance of the two models is assessed using extensive laboratory data (i.e., snapshots of a grid). While both models are able to properly adjust the GCPs, the simpler model gives a better overall performance when the GCPs are not well distributed over the image. Furthermore, the simpler model allows for better recovery of the camera position and orientation.

Abstract:
AbstractRadio snapshot imaging is an efficient observing method which allows several sources to be observed in the one session. Snapshot observing with the Australia Telescope Compact Array (ATCA) involves special difficulties, as the small number of antennas combined with the short total integration time leads to high sidelobe levels in the raw images. The images can be improved markedly by standard deconvolution techniques, but more care is required in their use because of the difficulty in distinguishing real emission from artefacts. This study, based on a set of snapshot observations of strong sources at 5 GHz, gives guidance on both the planning of observations and the data reduction. We show that snapshot imaging with the 6 km ATCA can achieve a dynamic range of 100–200:1 provided certain conditions are met, namely a peak flux density > 100 mJy, an angular size ≤ 30″ and an hour-angle coverage spanning at least six well-separated 5-minute cuts. When observing weak sources it is essential for calibration sources to be selected carefully and observed frequently.

Abstract:
At this meeting, powerful new images and spectroscopy of AGB stars were presented. Theoretical models have advanced, and we are learning more from studies of the pre-solar grains isolated from meteorites.We suggest that several mass loss mechanisms may be operating in AGB stars: current images imply both spherical winds and highly flattened outflows. There are good arguments that in some cases, a companion may be critical in driving the final outflow. In the near future, a number of extremely powerful new instruments and techniques will be available that will lead to a much deeper understanding of these systems.

Abstract:
Abstract. The response of cloud processes to an aerosol perturbation is one of the largest uncertainties in the anthropogenic forcing of the climate. It occurs at a variety of timescales, from the near-instantaneous Twomey effect to the longer timescales required for cloud adjustments. Understanding the temporal evolution of cloud properties following an aerosol perturbation is necessary to interpret the results of so-called “natural experiments” from a known aerosol source such as a ship or industrial site. This work uses reanalysis wind fields and ship emission information matched to observations of ship tracks to measure the timescales of cloud responses to aerosol in instantaneous (or“snapshot”) images taken by polar-orbiting satellites. As in previous studies, the local meteorological environment is shown to have a strong impact on the occurrence and properties of ship tracks, but there is a strong time dependence in their properties. The largest droplet number concentration (Nd) responses are found within 3 h of emission, while cloud adjustments continue to evolve over periods of 10 h or more. Cloud fraction is increased within the early life of ship tracks, with the formation of ship tracks in otherwise clear skies indicating that around 5 %–10 % of clear-sky cases in this region may be aerosol-limited. The liquid water path (LWP) enhancement and the Nd–LWP sensitivity are also time dependent and strong functions of the background cloud and meteorological state. The near-instant response of the LWP within ship tracks may be evidence of a bias in estimates of the LWP response to aerosol derived from natural experiments. These results highlight the importance of temporal development and the background cloud field for quantifying the aerosol impact on clouds, even in situations where the aerosol perturbation is clear.

Abstract:
Les caméras multispectrales échantillonnent le spectre du visible et/ou de l'infrarouge selon des bandes spectrales étroites. Parmi les technologies disponibles, Les caméras snapshot équipées d'une mosaïque de filtres acquièrent des images brutes à cadence vidéo. Ces images brutes nécessitent un processus de dématriçage permettant d'estimer l'image multispectrale en pleine définition. Dans ce manuscrit nous examinons les méthodes de dématriçage multispectrale et proposons une nouvelle méthode basée sur l'image panchromatique. De plus, nous mettons en évidence l'influence de l'illumination sur les performances de dématriçage, puis nous proposons des étapes de normalisation rendant ce dernier robuste aux propriétés d'acquisition. Les résultats expérimentaux montrent que notre méthode fournit de meilleurs résultats que les méthodes classiques.Afin d'effectuer une analyse de texture, nous étendons les opérateurs basés sur les motifs binaires locaux aux images de texture multispectrale au détriment d'exigences de mémoire et de calcul accrues. Nous proposons alors de calculer les descripteurs de texture directement à partir d'images brutes, ce qui évite l'étape de dématriçage tout en réduisant la taille du descripteur. Afin d'évaluer la classification sur des images multispectrales, nous avons proposé la première base de données multispectrale de textures proches dans les domaines spectraux du visible et du proche infrarouge. Des expériences approfondies sur cette base montrent que le descripteur proposé a à la fois un coût de calcul réduit et un pouvoir de discrimination élevé en comparaison avec les descripteurs classiques appliqués aux images dématriçées
Multispectral cameras sample the visible and/or the infrared spectrum according to narrow spectral bands. Available technologies include snapshot multispectral cameras equipped with filter arrays that acquire raw images at video rate. Raw images require a demosaicing procedure to estimate a multispectral image with full spatio-spectral definition. In this manuscript we review multispectral demosaicing methods and propose a new one based on the pseudo-panchromatic image. We highlight the influence of illumination on demosaicing performances, then we propose pre- and post-processing normalization steps that make demosaicing robust to acquisition properties. Experimental results show that our method provides estimated images of better objective quality than classical ones.Multispectral images can be used for texture classification. To perform texture analysis, we extend local binary pattern operators to multispectral texture images at the expense of increased memory and computation requirements. We propose to compute texture descriptors directly from raw images, which both avoids the demosaicing step and reduces the descriptor size. In order to assess classification on multispectral images we have proposed the first significant multispectral database of close-range textures in the visible and near infrared spectral domains. Extensive experiments on this database show that the proposed descriptor has both reduced computational cost and high discriminating power with regard to classical local binary pattern descriptors applied to demosaiced images

Abstract:
This thesis describes the improvements to the image replicating imaging spectrometer (IRIS) and the development of novel applications in the field of oximetry. IRIS is a snapshot multispectral device with a high transmission output and no need of inversion for data recovering, hence, with high signal-to-noise ratio (SNR). IRIS shows great versatility due to the possibility of choosing multiple contiguous or non-contiguous wavelengths inside its free spectral range. IRIS uses a set of waveplates and Wollaston prisms to demultiplex the spectral information of an object and replicate the image of such object in different wavelengths. The birefringent nature of IRIS means that different wavelengths are separated by the Wollaston prisms with different angles, introducing multiple images of the same object. In addition, the spectral transmission function shows multiple spectral sidelobes that contaminate each IRIS band with light belonging to other wavelengths. These issues can lower the performance of IRIS as a multispectral imaging device. In this thesis, these problems were assessed with the introduction of a filter plate array placed in the image plane of the optical system. This filter array is a set of narrow-band filters (Full Width Half Maximum (FWHM) =10 ± 2 nm ) that removes undesired wavelengths from each IRIS band. Since the spectral transmission of IRIS is replicated along the free spectral range, the filters can be designed to match any of the present spectral lobes in IRIS. The design and fabrication of a filter array enhance the performance of IRIS as a multispectral imaging device: it allows wavelength selection and improves spectral and spatial image quality. The design and manufacture of the corresponding filter holder and camera adapter were critical in terms of offering an easy filter-camera implementation. The filter plate allowed the removal of other dispersed wavelengths by the Wollaston prisms, improving image registration between the set of spectral images created by IRIS, and so, improving the quality of the registered spectral 3-D cube. The implemented improvements on IRIS allow high quality, calibration-free oximetry using eight different wavelengths optimised for oximetry. Two main experiments were performed: 1) Using an inverted microscopy interfaced with IRIS and a linear spectral unmixing technique, we measured the deoxygenation of single horse red blood cells (RBC) in vitro in real time. The oximetry was performed with a subcellular spatial resolution of 0.5 μ m , a temporal resolution of 30 Hz, and an accuracy (standard error of the mean) of ± 1.1% in oxygen saturation. 2) Eight-wavelength calibration-free retinal oximetry performed in nine healthy subjects demonstrated an increase in the stability of the oxygen saturation measurements along retinal vessels when compared with more traditional analysis methods such as two wavelengths oximetry. The stability was measured as the standard deviation along the retinal vessels of the nine subjects and was found to be ∼ 3% in oxygen saturation for eight-wavelengths oximetry and ∼ 5% in oxygen saturation for two-wavelengths oximetry. A modified physical model was used to improve the characterization of light propagation through the eye, retina, and blood vessels by applying a set of feasible physiological assumptions. This model was optimised by an algorithm which solves for the different variables involved in the retinal vessels transmissions in order to accurately calculate the oxygen saturation. The oximetry algorithm was applied in retinal vessels, in collaboration in vivo on rat spinal cord to assess hypoxia in inflammatory diseases such as multiple sclerosis and rheumatoid arthritis and on mice legs to assess hypoxia on autoimmune diseases. A third experiment using a microscope interfaced with IRIS was performed. The experiment aimed to replicate laminar flow conditions observed in retinal vessels and to calculate oxygen diffusion between adjacent streams of blood with different oxygen saturation. For this purpose a PDMS multichannel flow cell with cross sections of 40x100 μm was designed and fabricated allowing us to replicate conditions found in retinal blood vessels. Laminar flow was replicated but the experiment failed in calculating oxygen diffusion due to flaws in the experiment. The experiment with the results and recommendations on how to improve it can be found in Apendix B for future researchers.

Abstract:
This thesis explores the image-replicating imaging spectrometer (IRIS). This relatively recent invention is a two-dimensional, snapshot spectral-imaging technology, capable of recording the spectral and spatial data from a scene instantaneously. Whereas conventional spectral-imaging technologies require multiple detector frames to record the entire data set, IRIS is able to record the data set in a single frame, a capability which is useful for highly dynamic scenes. The IRIS concept and the design of IRIS systems are explained in detail, and constraints on the performance of IRIS are determined. Practical issue in the use of IRIS systems are identi ed and solutions are identi ed and appraised. Some applications of IRIS are also shown, demonstrating its viability as a spectral imaging technology. Novel aspects of this work include the re nement of the IRIS design, demonstration of a registration algorithm for IRIS, designs for achromatic Wollaston prisms, a comparison of the IRIS technology with conventional spectral imaging technologies, and the application of IRIS to practical problems.

Abstract:

An investigation was initiated, targeting snapshot 3D image sensors, with the objective to match the speed and resolution of a scanning sheet-of-light system, without using a scanning motion. The goal was a system capable of acquiring 25 snapshot images per second from a quadratic scene with a side from 50 mm to 1000 mm, sampled in 512×512 height measurement points, and with a depth resolution of 1 µm and beyond.

A wide search of information about existing 3D measurement techniques resulted in a list of possible schemes, each presented with its advantages and disadvantages. No single scheme proved successful in meeting all the requirements. Pulse modulated time-of-flight is the only scheme capable of depth imaging by using only one exposure. However, a resolution of 1 µm corresponds to a pulse edge detection accuracy of 6.67 fs when visible light or other electromagnetic waves are used. Sequentially coded light projections require a logarithmic number of exposures. By projecting several patterns at the same time, using for instance light of different colours, the required number of exposures is reduced even further. The patterns are, however, not as well focused as a laser sheet-of-light can be.

Using powerful architectural concepts such as matrix array picture processing (MAPP) and near-sensor image processing (NSIP) a sensor proposal was presented, designed to give as much support as possible to a large number of 3D imaging schemes. It allows for delayed decisions about details in the future implementation.

It is necessary to relax at leastone of the demands for this project in order to realise a working 3D imaging scheme using concurrent technology. One of the candidates for relaxation is the most obvious demand of snapshot behaviour. Furthermore, there are a number of decisions to make before designing an actual system using the recommendations presented in this thesis. The ongoing development of electronics, optics, and imaging schemes might be able to meet the 3D snapshot demands in a near future. The details of light sensing electronics must be carefully evaluated and the optical components such as lenses, projectors, and fibres should be studied in detail.

Abstract:
Conventional hyperspectral imaging (HSI) techniques are time-sequential and rely on temporal scanning to capture hyperspectral images. This temporal constraint can limit the application of HSI to static scenes and platforms, where transient and dynamic events are not expected during data capture. The Near-Infrared Image Replicating Imaging Spectrometer (N-IRIS) sensor described in this thesis enables snapshot HSI in the short-wave infrared (SWIR), without the requirement for scanning and operates without rejection in polarised light. It operates in eight wavebands from 1.1μm to 1.7μm with a 2.0° diagonal field-of-view. N-IRIS produces spectral images directly, without the need for prior topographic or image reconstruction. Additional benefits include compactness, robustness, static operation, lower processing overheads, higher signal-to-noise ratio and higher optical throughput with respect to other HSI snapshot sensors generally. This thesis covers the IRIS design process from theoretical concepts to quantitative modelling, culminating in the N-IRIS prototype designed for SWIR imaging. This effort formed the logical step in advancing from peer efforts, which focussed upon the visible wavelengths. After acceptance testing to verify optical parameters, empirical laboratory trials were carried out. This testing focussed on discriminating between common materials within a controlled environment as proof-of-concept. Significance tests were used to provide an initial test of N-IRIS capability in distinguishing materials with respect to using a conventional SWIR broadband sensor. Motivated by the design and assembly of a cost-effective visible IRIS, an innovative solution was developed for the problem of chromatic variation in the splitting angle (CVSA) of Wollaston prisms. CVSA introduces spectral blurring of images. Analytical theory is presented and is illustrated with an example N-IRIS application where a sixfold reduction in dispersion is achieved for wavelengths in the region 400nm to 1.7μm, although the principle is applicable from ultraviolet to thermal-IR wavelengths. Experimental proof of concept is demonstrated and the spectral smearing of an achromatised N-IRIS is shown to be reduced by an order of magnitude. These achromatised prisms can provide benefits to areas beyond hyperspectral imaging, such as microscopy, laser pulse control and spectrometry.

Se explora la compleja fascinación que la fotografía despierta como medio de expresión, en la que se destaca la captura de imágenes en sí, como posibilidad para establecer un diálogo con el entorno y con uno mismo. Considerando que a partir de la integración de la cámara fotográfica al teléfono móvil, fotografiar se convierte en una experiencia que se integra a la vida cotidiana y, prácticamente, al alcance de casi cualquiera. Ello evidencia un tipo de imagen particular, que se ha denominado ‘imagen fortuita’. Se instaura este término con la finalidad de delimitar y caracterizar una especificidad de la llamada postfotografía, una comprensión de la práctica fotográfica que contempla uso, función y concepción del propio medio, con el fin de aproximarnos a la naturaleza de la fotografía mediante este dispositivo. Se ejemplifica la ‘imagen fortuita’ a partir de una selección de imágenes de las primeras ediciones del concurso ‘iPPAWARDS’.
This research explores the complex fascination that photography arouses as a medium of expression, it emphasizes the photographic act per se, due to its potential to establish a dialogue with the environment and with oneself. It is stated that after integration of a camera into mobile phone, photographic act becomes an everyday experience, available to almost anyone, and, it originates a particular type of image that we have named 'fortuitous image'. This term is established in order to capture, define and characterize a moment of denominated post-photography to approach the understanding of its nature. The 'fortuitous image' is exemplified by an image selection of the first editions of ‘iPPAWARDS’ contest.

Abstract:
During the twentieth century, men and women across Ireland picked up cameras, photographing days out at the beach, composing views of Ireland’s cities and countryside, and recording political events as they witnessed them. Indeed, while foreign photographers often focused on the image of Ireland as a bucolic rural landscape, Irish photographers—snapshotter and professional alike—were creating and curating photographs of Ireland which revealed more complex and diverse images of Ireland. Snapshot Stories explores these stories. It examines a diverse array of photographic sources, including family photograph albums, studio portraits, and the work of photography clubs and community photography initiatives, alongside the output of those who took their cameras into the streets to record violence and poverty. It shows how Irish men and women used photography in order to explore their sense of self and society, and examines how we can use these images to fill in the details of Ireland’s social history. Through exploring this rich array of sources, it asks what it means to see—to look, to gaze, to glance—in modern Ireland, and explores how conflicts regarding vision and visuality have repeatedly been at the centre of Irish life.

Abstract:
Snapshot Stories concludes as the twentieth century ends, and paper photographs and analogue cameras are replaced by digital images and new technologies. However, the final chapter provides an examination of how some of the themes explored throughout the earlier chapters have adapted since the close of the century. Indeed, it is arguable that the themes addressed throughout this book have only become of greater relevance in the twenty-first century, as the visual has increasingly played a more pressing role in everyday life and political culture. Photograph albums have now been deposed by photographs on social media as a forum for displaying and curating identity. The photographers who stood with their cheap cameras on top of Derry tower blocks in 1969 today seem to be the ancestors of activists who record police violence on smartphones. However, just as the shift to the digital is producing an image saturated culture which seems to offer new modes of political participation and personal self-fashioning, it also poses fundamental questions for the historian. Online databases of images open up newly accessible source bases, but they also require new methods to work in them, while the certainties of cutting, pasting, and annotating of photograph albums and framed photographs have now disappeared in the new image-culture of the twenty-first century. The final pages of the book bring all these themes together by briefly examining photo culture in modern Ireland, scrutinizing how archival practices are changing, historical questions are being reshaped, and looking ahead to the challenges and potentials for the future of work on photography.

Abstract:
Proper Orthogonal Decomposition (POD) offers an approach to quantify cycle-to-cycle variation (CCV) of the flow field inside the internal combustion engine cylinder. POD decomposes instantaneous flow fields (also called snapshots) into a series of orthonormal flow patterns (called POD modes) and the corresponding mode coefficients. The POD modes are rank-ordered by decreasing kinetic energy content, and the low-order, high-energy modes are interpreted as constituting the large-scale coherent flow structure that varies from engine cycle to engine cycle. Various POD-based analysis techniques have thus been proposed to characterize engine flow field CCV using these low-order modes. The validity of such POD-based analyses rests, as a matter of course, on the reliability of the underlying POD results (modes and coefficients). Yet a POD mode can be disproportionately skewed by a single outlier snapshot within a large data set, and an algorithm exists to define and identify such outliers. In this paper, the effects of a candidate outlier snapshot on the results of POD-based conditional averaging and quadruple POD analyses are examined for two sets of crank angle-resolved flow fields on the mid-tumble plane of an optical engine cylinder recorded by high-speed particle image velocimetry. The results with and without the candidate outlier are compared and contrasted. In the case of POD-based conditional averaging, the presence of the outlier scrambles the composition of snapshot subsets that define large-scale flow pattern variations, and thus substantially alters the coherent flow structures that are identified; for quadruple POD, the shape of coherent structures as well as the number of modes to define them are not significantly affected by the outlier.
