In spite of the strong efforts accomplished by past and current instruments, in order to perform observations in this energy range, an improvement in sensitivity over present technologies is needed to take full advantage of the scientific potential contained in this energy range. In order to achieve higher sensitivities, γ-ray astronomy has been looking over the last decades for new ways to increase the efficiency of its instruments while reducing the background noise. With the objective of reducing or avoiding as much background as possible (through shielding mechanisms and data analysis techniques), a strong effort in innovation and design (build-up of prototypes and numerical simulations studies) is being conducted by a community facing the challenge of preparing the next generation of γ-ray telescopes. In particular, the progress achieved during the last decade on focusing optics based on Laue lenses is especially remarkable. Conceptually, a focusing telescope will reduce drastically the background noise by concentrating γ-rays onto a small size detector. Focusing γ-rays with a Laue lens is not just a theoretical concept, but a reality, mainly thanks to the development of a first prototype of Laue lens for nuclear astrophysics accomplished as part of the CLAIRE project. Moreover, the development of focusing optics during these years has also encouraged the development of new detector technologies. The focal plane detector of a focusing telescope should provide imaging capabilities, perform high-resolution spectroscopy and measure the polarization of the incident photons in order to achieve the ambitious scientific goals. The research presented in this thesis covers both main areas of a γ-rays telescope: focusing optics and focal plane detector. As far as the optics is concerned, a test of the lens CLAIRE was performed in order to confirm the principles of a Laue diffraction lens. Concerning the focal plane detector, theoretical and experimental studies with new detector technologies have been carried out. Our main research has evolved in the framework of two mission concept studies -GRI (2007) and DUAL (2010)- submitted to the ESA Calls for a Medium-size mission opportunity within the Cosmic Vision 2015-2025 program. As far as the GRI mission is concerned, a focal plane detector configuration based on Cd(Zn)Te pixelated detectors is proposed, whilst development and testing of a detector prototype is accomplished. It is noteworthy that the detector configuration was successfully registered under a European Patent and is being considered for applications in the field of nuclear medicine. Regarding the DUAL mission, simulations of the expected space radiation environment and the resulting detector activation were carried out in order to estimate the performances of the all-sky Compton telescope of DUAL (based on Germanium-strip detectors). The results show that DUAL could achieve, after two years of operation, a continuum sensitivity one order of magnitude better than any past and current observatory in the MeV energy range and up to a factor 30 of improvement with its Laue lens. Beyond the detector technology proposed for GRI and DUAL, a wide variety of technologies could be explored for the focal plane of a γ-ray lens mission as well as for a stand-alone detector. In this thesis a focal plane detector based on liquid xenon is also considered. This work faces the challenges of the next generation of γ-ray telescopes, where high performance γ-ray detectors are necessary to achieve the required sensitivity in order to answer several hot scientific topics of Gamma-ray astrophysics in the energy range of nuclear transitions.

Full textThe removal of the sensor signature in the science images has been identified by the LSST Dark Energy Science Collaboration as a mandatory path to fullfill its scientific goals. The SAWG working group has been put together to perform this task for the collaboration. It has access to optical benches in some of the laboratories of the collaboration (UC Davis, SLAC, BNL and LPNHE) for this purpose. LSST belongs to a new category of telescopes equiped with large focal planes. For the decade that they have been equipped with thick, high resistivity Charge Coupled Devices (CCD), new effects have been identified. A particular attention is given to the understanding of the electrostatic distortions that are inherent to the CCD properties. These electrostatic distortions have an impact on science measurements. My PhD work is centered on the study of the brighter-fatter effect and the tree-rings. It has been shown that with different kind of illuminations, it was possible to accurately characterize these effects. A fringe projector has been developed on the optical bench of the LPNHE in order to produce these particular illuminations. In this document, we present : a new method, tested on simulations, to characterize the tree-rings; a new method to measure the brighter-fatter effect based on the projection of Ronchi profiles; a complete study of the different properties of the brighter-fatter effect, where we developped a simplified electrostatic model. Finally, the efficiency of a correction method, called descrambling, is evaluated

Full textIn order to increase the sky coverage in Adaptive Optics (AO), Laser Guide Stars (LOS) are created in the Sodium layer of the atmosphere. These 3D extended objects induce specific problems on the wave front measurement performed by the Wave Front Sensor (WFS). Some of these problems become critical on the Extremely Large Telescopes (ELTs). The goal of this work is to study the specificity of the wavefront analysis on LGS in the framework of the ELTs, and to optimize the WFS measurement accuracy on such objects. We first studied the characterization of the effects of differential focal anisoplanatism on wave front measurements. Using a diffractive propagation model,i. E. Taking into account the effects of phase and amplitude, we have calculated these effects in the case of ELTs. Considering the stage of tomographic phase reconstruction. We have shown that these effects are actually low in amplitude for most applications. We proposed then a simple model to classify the different sources of errors identified in the literature. After showing that the Pyramid WFS and the Shack-Hartmann (SH) had very similar behaviours with regards to these effects, we assessed the différent error terms in the decomposition, considering the case of a SH WFS. We studied in detail the evaluation of the non-linearity error and the sensor noise error. Then we evaluated the impact of the Sodium layer variations, considering analytical profiles as well as real data. We considered also here the stage of tomographic reconstruction. Finally, we managed to deduce from this study the parameters of the WFS to be favored when optimizing the wavefront analysis on LGS, in the case of ELTs

Full textPurpose: To compare the conventional telescope (CT) with the contact lens telescope (CLT) in patients with age-related macular degeneration (AMD) and low-vision, with respect to visual acuity (VA), visual field (VF), patient satisfaction with the vision provided by the telescope (VS), telescope use difficulties (UD) and patient satisfaction with the cosmetic appearance of the telescope (CS). Methods: In a masked randomized clinical trial, 12 patients with AMD and low-vision were enrolled in 2 groups with 6 patients each: group 1 (CLT use) and group 2. (CT use) The telescopes used in this study were standardized to have the same magnification power. (2.8x) Visual field and VA were obtained before and during the telescope use, while VS, UD and CS were obtained after the telescope use. Results: There were no significant differences between groups at baseline. Both groups achieved VA improvement with telescopes compared to baseline (P=0.002 in CLT group and P<0.001 in CT group) and there were no significant differences between groups in this regard. Visual field was reduced by 15° in CLT group (P<0.001) and by 54.3° in CT group (P<0.001) compared to baseline, and VF differences between groups were also significant during telescope use. (P<0.001) Scores observed in both groups were similar in regard to VS. Telescope use difficulties were significant higher in CLT group (P=0.003) as well as CS scores (P<0.001) compared to CT group. Conclusions: Both telescopes provide similar improvement in VA in AMD patients with low-vision, but CLT caused less VF reduction than CT use. Patient satisfaction with the cosmetic appearance of the telescope was higher in CLT group, but UD was also higher in this group compared to CT group.
