Esta tesis describe trabajos de laboratorio, que tienen como objetivo generar y caracterizar fotones individuales y pares de fotones, aptos para interactuar con átomos fríos. Para este fin, el espectro conjunto o contenido en frecuencia de los fotones pares es de particular interés. El átomo considerado en la tesis es rubidio. Primero describimos una fuente de pares de fotones, basada en el proceso de conversión paramétrica descendente espontánea (spontaneous parametric down-conversion, SPDC por sus siglas en inglés), aumentada por un resonador óptico (cavity-enhanced SPDC, o CE-SPDC). Este proceso genera pares de fotones de banda estrecha, con un ancho de banda de ≈5MHz Ambos fotones producidos por la fuente concuerdan en frecuencia con la línea D1 del rubidio atómico. La coincidencia de fases (phase matching) de tipo dos, un resonador de birrefringencia ajustable, y una bomba de frecuencia ajustable con resolución de unos MHz, son usados para conseguir control independiente sobre la frecuencia de cada fotón del par, con precisión de MHz, permitiendo que exciten diferentes transiciones hiperfinas del rubidio. Diseñamos e implementamos filtros Fabry-Perot sintonizables, también con una precisión de control de _ MHz en su frecuencia de resonancia. Con dichos filtros, demostramos la selección de pares de fotones que provienen, cada uno, de un solo modo del resonador, y por lo tanto con un ancho de banda definido por dicho modo. Los filtros tienen una transmisión del .̴ 90% en resonancia y extinguen componentes fuera de banda en 20 dB. Calculamos el espectro conjunto de los pares de fotones producidos, tanto a la salida de la fuente, como después de lo filtros, a base de modelos teóricos de CE-SPDC. Medimos el ancho de banda de ambos fotones, el número de modos de emisión en un cúmulo, el espaciado espectral entre grupos de modos cuasi-resonantes, y las funciones de correlación cruzada de segundo orden y de autocorrelación anunciada, y resultan estar en buen acuerdo con las predicciones. Demostramos un ajuste independiente de la frecuencia del fotón signal y del fotón idler mediante espectroscopía de absorción con la salida del CE-SPDC como fuente de luz. También presentamos una técnica para distinguir diferencias estrechas de frecuencia entre fotones con una gran resolución en frecuencia. Esta técnica, a la que llamamos caracterización autoheterodina, permite medir el espectro conjunto de un par de fotones mediante la detección de la correlación en tiempo de su batido (beat-note) cuando el par de fotones no-degenerados interfiere en un divisor de haz. Esta técnica implementa un análogo temporal al efecto Ghosh-Mandel con un contador de fotones y una interferencia Hong-Ou-Mandel con resolución temporal con dos. Proporcionamos una descripción teórica completa del proceso y mostramos como la distribución de la suma y diferencia de frecuencias en el espectro del par de fotones puede obtenerse a partir de las medidas de las funciones de correlación. Mediante el análisis del espectro de las medidas de correlación, se obtienen las amplitudes, anchos de línea y frecuencias relativas del contenido espectral del estado conjunto de los dos fotones. Con esto, es posible cuantificar la presencia de modos indeseados de frecuencia cuando se requiere una salida monomodo. Analizamos la aplicación de esta técnica a pares de fotones producidos por bombeo de banda estrecha y fuertemente anti-correlacionados en frecuencia, y a pares con correlaciones de frecuencia reducidas producidos por bombeo de banda ancha. Experimentalmente, demostramos esta técnica usando pares de fotones generados por la fuente descrita en el párrafo anterior, con una separación en frecuencia de .̴ 200MHz. A partir de los resultados, cuantificamos el desempeño de los filtros y verificamos la exactitud de nuestro modelo para el espectro conjunto de los dos fotones provenientes de la fuente CE-SPDC con filtros.

feature extraction, classification and road detection. Well-known spectral band ratios are utilized to represent reflectance properties of the data whereas a segmentation operation followed by an elongatedness scoring technique renders structural evaluation of the road parts within the multi-resolution analysis framework. The extracted features are fed into Adaptive Boosting (Adaboost) learning procedure, and the learning method iteratively combines decision trees to acquire a classifier with a high accuracy. The road network is identified from the probability map constructed by the classifier suggested by Adaboost. The algorithm is designed to be modular in the sense of its extensibility, that is
new road descriptor features can be easily integrated into the existing model. The empirical evaluation of the proposed algorithm suggests that the algorithm is capable of extracting majority of the road network, and it poses promising performance results.

Al, saddik Hania. "Spectral and textural analysis of high resolution data for the automatic detection of grape vine diseases". Thesis, Bourgogne Franche-Comté, 2019. http://www.theses.fr/2019UBFCK050/document.
‘Flavescence dorée’ is a contagious and incurable disease present on the vine leaves. The DAMAV project (Automatic detection of Vine Diseases) aims to develop a solution for automated detection of vine diseases using a micro-drone. The goal is to offer a turnkey solution for wine growers. This tool will allow the search for potential foci, and then more generally any type of detectable vine disease on the foliage. To enable this diagnosis, the foliage is proposed to be studied using a dedicated high-resolution multispectral camera.The objective of this PhD-thesis in the context of DAMAV is to participate in the design and implementation of a Multi-Spectral (MS) image acquisition system and to develop the image pre-processing algorithms, based on the most relevant spectral and textural characteristics related to ‘Flavescence dorée’.Several grapevine varieties were considered such as red-berried and white-berried ones; furthermore, other diseases than ‘Flavescence dorée’ (FD) such as Esca and ‘Bois noir’ (BN) were also tested under real production conditions. The PhD work was basically performed at a leaf-level scale and involved an acquisition step followed by a data analysis step.Most imaging techniques, even MS, used to detect diseases in field crops or vineyards, operate in the visible electromagnetic radiation range. In DAMAV, it is advised to detect the disease as early as possible. It is therefore necessary to investigate broader information in particular in the infra-red. Reflectance responses of plants leaves can be obtained from short to long wavelengths. These reflectance signatures describe the internal constituents of leaves. This means that the presence of a disease can modify the internal structure of the leaves and hence cause an alteration of its reflectance signature.A spectrometer is used in our study to characterize reflectance responses of leaves in the field. Several samples at different growth stages were used for the tests. To define optimal reflectance features for grapevine disease detection (FD, Esca, BN), a new methodology that designs spectral disease indices based on two dimension reduction techniques, coupled with a classifier, has been developed. The first feature selection technique uses the Genetic Algorithms (GA) and the second one relies on the Successive Projection Algorithm (SPA). The new resulting spectral disease indices outperformed traditional vegetation indices and GA performed in general better than SPA. The features finally chosen can thus be implemented as filters in the MS sensor.In general, the reflectance information was satisfying for finding infections (higher than 90% of accuracy for the best method) but wasn’t enough. Thus, the images acquired with the developed MS device can further be pre-processed by low level techniques based on the calculation of texture parameters injected into a classifier. Several texture processing techniques have been tested but only on colored images. A method that combines many texture features is elaborated, allowing to choose the best ones. We found that the combination of optimal textural information could provide a complementary mean for not only differentiating healthy from infected grapevine leaves (higher than 85% of accuracy), but also for grading the disease severity stages (higher than 73% of accuracy) and for discriminating among diseases (higher than 72% of accuracy). This is in accordance with the hypothesis that a multispectral camera can enable detection and identification of diseases in grapevine fields

Spectrally resolved infrared radiances measured from orbit with extremely high absolute accuracy constitute a critical observation for future climate benchmark missions. For the infrared radiance spectra, it has been determined that a measurement accuracy, expressed as an equivalent brightness temperature error, of 0.1 K confirmed on orbit is required for signal detection above natural variability for decadal climate signatures. The University of Wisconsin Space Science and Engineering Center (UW-SSEC), with funding support from the NASA Instrument Incubator Program (IIP), developed the Absolute Radiance Interferometer (ARI). The ARI is designed to meet the uncertainty requirements needed to establish a spectrally resolved thermal infrared climate benchmark measurements from space. The challenge in the infrared sensor development for a climate benchmark measurement mission is to achieve this ultra-high accuracy with a design that can be flight qualified, has long design life, and is reasonably small, simple, and affordable. In this area, our design approach for the Absolute Radiance Interferometer (ARI) made use of components with strong spaceflight heritage (direct analogs with high TRL) combined into a functional package for detailed performance testing. The required simplicity is achievable due to the large differences in the sampling and noise requirements for the benchmark climate measurement from those of the typical remote sensing infrared sounders for weather research or operations. The new aspect of the interferometer development is the ultra high absolute accuracy sought, and is the subject of this thesis. The goal of this effort is to successfully demonstrate this measurement capability under laboratory and vacuum conditions, over a subset of the range of equivalent earth scene brightness temperatures expected on-orbit. Advances in instrumental aspects have been achieved in the pursuit of this goal.

A aquisicção de grandes volumes de dados durante uma campanha sísmica exige, necessariamente, mais tempo para o controlo de qualidade (QC). No entanto, o tempo de QC não pode ser extendido devido a limitações do tempo de operação, tendo de ser feito mais rápido, o que pode comprometer a qualidade. A alternativa, alocar mais pessoas e recursos para QC e melhorar a eficiência, leva a aumentos de custo e à necessidade de maiores embarcações. Além disso, o QC tradicional requer tempo de análise após a aquisição, atrasando a desmobilização da embarcação, aumentando assim os custos da aquisição. A solução proposta passou pelo desenvolvimento de um QC automático em tempo real eficiente, testando a Comparação Espetral e o Atributo Razão Sinal-Ruído - ferramentas desenvolvidas no software SPW, usado para processamento de dados sísmicos. Usando este software foi testada a deteção e identificação de dados de fraca qualidade através das ferramentas de QC automáticas e os seus parâmetros ajustados para incluir pelo menos todos os maus registos encontrados manualmente. Foi também feita a deteção e identificação de vários problemas encontrados durante uma campanha de aquisição, tais como fortes ondulações e respetiva direção, o ruído de esteira provocado pelas hélices da embarcação e consequente Trouser’s Effect e mau funcionamento das fontes ou dos recetores. A deteção antecipada destes problemas pode permitir a sua resolução atempada, não comprometendo a aquisição dos dados. Foram feitos vários relatórios para descrever problemas encontrados durante os testes de versões beta do software SPW e os mesmos reportados à equipa da Parallel Geoscience, que atualizou o software de forma a preencher os requisitos necessários ao bom funcionamento do QC em tempo real. Estas atualizações permitiram o correto mapeamento dos headers dos ficheiros, otimização da velocidade de análise das ferramentas automáticas e correção de erros em processamento dos dados em multi-thread, para evitar atrasos entre o QC em tempo real e a aquisição dos dados, adaptação das ferramentas à leitura de um número variável de assinaturas das fontes, otimização dos limites de memória gráfica e correção de valores anómalos de semelhança espetral. Algumas atualizações foram feitas através da simulação da aquisição de dados na empresa, de forma a efetuar alguns ajustes e posteriormente serem feitos testes numa campanha futura. A parametrização destas ferramentas foi alcançada, assegurando-se assim a correta deteção automática dos vários problemas encontrados durante a campanha de aquisição usada para os testes, o que levará à redução do tempo gasto na fase de QC a bordo e ao aumento da sua eficácia.
The acquisition of larger volumes of seismic data during a survey requires, necessarily, more time for quality control (QC). Despite this, QC cannot be extended due operational time constraints and must be done faster, compromising its efficiency and consequently the data quality. The alternative, to allocate more people and resources for QC to improve efficiency, leads to prohibitive higher costs and larger vessel requirements. Therefore, traditional QC methods for large data require extended standby times after data acquisition, before the vessel can be demobilized, increasing the cost of survey. The solution tested here consisted on the development of an efficient Real- Time QC by testing Spectral Comparison and Signal to Noise Ratio Attribute (tools developed for the SPW seismic processing software). The detection and identification of bad data by the automatic QC tools was made and the parameters adapted to include at least all manual QC flags. Also, the detection and identification of common problems during acquisition, such strong wave motion and its direction, strong propeller’s wash, trouser’s effect and malfunction in sources or receivers were carried out. The premature detection of these problems will allow to solve them soon enough to not compromise the data acquisition. Several problem reports from beta tests of SPW were transmitted to the Parallel Geoscience team, to be used as a reference to update the software and fulfil Real-Time QC requirements. These updates brought the correct mapping of data headers in files, optimization of data analysis speed along with multi-thread processing debug, to assure it will be running fast enough to avoid delays between acquisition and Real-Time QC, software design to read a variable number of source signatures, optimization of graphic memory limits and debugging of anomalous spectral semblance values. Some updates resulted from a data acquisition simulation that was set up in the office, to make some adjustments to be later tested on an upcoming survey. The parameterization of these tools was finally achieved, assuring the correct detection of all major issues found during the survey, what will eventually lead to the reduction of time needed for QC stage on board, as also to the improvement of its efficiency.

The IASI hyperspectral infrared sounding interferometer, the first model of which has been flown on board the meteorological polar orbiting satellite MetOp-A since 2006, has already led to spectacular scientific breakthroughs in both weather forecasting and research into atmospheric composition and the climate. Measurements from the sounders are however largely underutilised, mainly because of the presence of clouds in the atmosphere. The highly non-linear way in which the clouds interact with incident radiation makes analysis of the readings much more complex, and can sometimes even prohibit access from space to the properties of not only the atmospheric layers located above the cloud, but also below them in the case of semi-transparency. However, in view of the potential amount of information offered by the sounders, the scientific community is very interested in exploiting cloud radiance. The research for this thesis stems from this interest. We plan to study two radically different cloud schemes: cloud clarification and a scheme which allows for simulation of cloud radiance by using the optical and microphysical properties of clouds. The first of these methods, initiated by Smith et al. (1968), allows us under certain conditions to disregard the cloud in the IASI pixel. This method is based on the CNES Heterogeneous Scenes software algorithm. After a first validation step, method performance is evaluated by the amount of independent information offered by the clarification, compared to a cloud radiance process chain established at CMS. The results are favorable to the tested method allowing us to deal with atmospheric layers under the cloud, which have therefore larger quantities. However clarification is based on a strong assumption of atmospheric homogeneity and only applies to 15% of cloud situations. The second method is a simulation of cloud radiance by fast radiative transfer models using the optical and microphysical properties of the cloud. The major advantage of this method is that it uses the same cloud profiles as those produced by numerical weather prediction models, allowing assimilation of these profiles from the IASI measurement. However, the use of these fast radiative transfer models in the context of data assimilation is still in the early stages, very few studies have been conducted on this topic. We are proposing a three-phase study which will allow for an operational use of these radiative transfer models. The first step is validation. This is done by conducting several case studies based on Lindenberg’s measurement campaign. Then, within the framework of the ConcordIasi campaign, a statistical analysis will be carried out by introducing filtering, to select cloud profiles which are consistent with the IASI observations. The last step is an overall application, the statistics showing a clear improvement in deviation from the draft thanks to the filters, going from 8K to 2K. Throughout the study we will discuss the models used (RTTOV and HISCRTM), their strengths and weaknesses. Finally the last step allows us to evaluate the performance of the cloud profiles obtained by the digital forecasting models

LiDAR (an acronym for Light Detection and Ranging) is a technology that can be used to measure properties of the atmosphere. It is similar to radar, but uses much smaller light waves rather than larger radio waves, enabling more detailed information to be obtained. High Spectral Resolution Lidar (HSRL) is a lidar technique that uses a high precision optical filter to distinguish between light that scatters from particulates (such as dust, smoke, or fog) and light that scatters from molecules (such as oxygen, nitrogen, or carbon dioxide) in the atmosphere. By separating the two types of backscattered light, higher accuracy measurements are possible that will enable improvements in climate models, air quality measurements, and climate forecasting. A spaceborne HSRL instrument can provide great impact in these areas by enabling near-continuous measurements across the Earth; however, the optical filter technology has typically been too complex for reliable long-duration spaceflight due to the need for complicated and expensive additional hardware. In this research, a high-performance HSRL optical filter that can be reliably operated by simply monitoring and adjusting the temperature has been designed, built, and tested. The greatly-reduced operational complexity has been made possible through a new process that enables more accurate prediction of the complicated interactions between the materials of the optical filter. This process is based on a combination of high-accuracy characterization of the materials and detailed structural-thermal-optical-performance (STOP) modeling. The overall design process, fabrication procedures, and characterization of the optical filter are presented.
