Full textSynchrotrons use a variety of mirrors for reshaping or redirecting X-ray beams. The mirrors can have lengths up to 1.5 m and surface figure errors below 1 nm. Characterization of these mirrors requires advanced metrology tools. More commonly used instruments are Long Trace Profilers (LTP), Nanometer Optical Component Measuring Machines (NOM), Fizeau interferometers and Micro interferometers. The Stitching Shack-Hartmann wavefront sensor (SHARPeR) is a novel 2D slope measuring instrument developed as an integrated commercial product by Imagine Optic and Q-Sys, and uses subaperture stitching algorithms to measure synchrotron mirrors. This thesis has improved the performance of the SHARPeR installed at ESRF. New measurement techniques have been developed to reduce errors from aberrations of optical elements. The impact of mechanical translation errors and environmental errors such as those from air turbulence and temperature fluctuations upon measurement repeatability and accuracy have been characterized, and consequent improvements have been made to the instrument design. The performance of subaperture stitching algorithms has been explored and an open source stitching software package has been developed with multiple working algorithms. The improved instrument performance has been verified using comparative measurements of various artefact mirrors, and comparing to results obtained from more established metrology instruments such as LTP, Fizeau and Micro-interferometers

Full textThe Laser Interferometer Space Antenna (LISA) is a space-based gravitational wave observatory now in Phase A. The measurements of the gravitational waves are performed by precise heterodyne interferometric measurements. If any light, which was not intended into the design (stray light), couples to the interfering beams, the measurements will be perturbed. Scattered light differs from other types of stray light (such as diffraction at apertures, stray reflection or transmission) in that it results from an unknown roughness profile or dust contamination distribution: no exact evaluation is possible. The thesis is dedicated to the studies of the consequences of the scattered light on interferometric measurements. When a rough surface is illuminated by a coherent, monochromatic beam of light, a scattering process takes place, and the scattered light shows a grainy structure called speckle. A similar pattern is also observed in the case of scattering from particulate contamination, or due to the irregularities in the structure of optical fibers. This thesis is devoted to the study of the scattering of coherent light, and the perturbation of the readout of an interferometer due to the presence of scattered light. For these studies of coherent light scattering, I use two approaches: numerical modeling and experimental measurements. I have developed a numerical model of coherent scattering due to microroughness. It is in agreement with the Harvey-Schack model of the Bidirectional Reflectance Distribution Function (BRDF). From the other side, it correctly describes the observed features of coherent scattering: amplitude and intensity distribution, the spatial dimension of the single speckle grain. Another numerical model, which I have developed, is used to describe coherent backscattering in optical fibers. The result of the model coincides with the conventional, incoherent model. In addition to this, it correctly describes the features of coherent scattering observed on an experiment made at the Albert Einstein Institut in Hannover: intensity distribution and temperature change rate.Two fibered, homodyne interferometric setups (at 1.55 µm and 1.06 µm) were built for experimental studies of the coherent scattering. These studies' necessity is driven by the need for an accurate description of coherent scattering effects in interferometric setups, such as LISA. Both setups have demonstrated the presence of a speckle type response. A signal processing algorithm was specially developed to measure low backscattering values from the optical surfaces. The measurement floor of the 1.06 µm setup reaches 10-13 in relative power, and 10-5 1/sr in BRDF, which matches modern, state-of-the-art BRDF meters.The same experimental setups were used to study coherent scattering due to contamination. The results of the measurements were compared with the Mie scattering theory. Besides this, I have used conventional methods to study scattered light due to micrometeoroid damage. The impact on an optical surface by a micrometeoroid gives rise to a specific type of stray light inherent only in space optical instruments. This causes a double source of light scattering: the impact crater, and the ejected contamination. I propose a method of stray light estimation and apply it to the case of the LISA telescope. I have estimated upper limits for the backscattering fraction for nominal (4 years) and extended (10 years) mission durations.This work brings an ensemble of experimental and modeling studies that improve the knowledge of the properties of coherently scattered light, and its consequences in high precision interferometric instruments

Full textFlow sensing is used by a vast number of animals in various ecological contexts, from preypredator interactions to mate selection, and orientation to flow itself. Among these animals, crickets use hundreds of filiform hairs on two cerci as an early warning system to detect remote potential predators. Over the years, the cricket hairs have been described as the most sensitive sensor in the animal kingdom. The energy necessary for the emission of an action potential by its sensory neuron was estimated to be a tenth of the energy of a photon. This PhD thesis aims to describe recent technological advances in the measurement and model of flows around biological and artificial flow sensors in the context of organismal sensory ecology. The study and understanding of the performance of sensory systems requires a high spatial precision of non-intrusive measurement methods. Thus, non-contacting measurement methods such as and Particle Image Velocimetry (PIV), originally developed by aerodynamics and fluid mechanics engineers, have been used to measure flows of biological relevance. The viscous oscillatory boundary layer surrounding filiform hairs has been visualized and used as input to model the mechanical response of these hairs, described as second order mechanical systems. The viscous hydrodynamic coupling occurring within hair canopy was also characterized using PIV measurements on biomimetic micro-electro-mechanical systems (MEMS) hairs, mimicking biological ones. Using PIV, we have also measured the air flow upstream of hunting spiders. We prove that this flow is highly conspicuous aerodynamically, due to substantial air displacement detectable up to several centimeters in front of the running predator. This disturbance of upstream air flows were also assessed by computational fluid dynamics (CFD) with the finite elements method (FEM). The development of non-intrusive measurement and CFD methods and their application to the analysis of the biological flow involved in cricket sensory ecology allowed us to revisit the extreme sensitivity of cricket filiform hairs. We predicted strong hydrodynamic coupling within natural hair canopies and we addressed why hairs are packed together at such high densities, particularly given the exquisite sensitivity of a single hair. We also proposed a new model of hair deflection during the arrival of a predator, by taking into account both the initial and long-term aspects of the flow pattern produced by a lunging predator. We conclude that the length heterogeneity of the hair canopy mirrors the flow complexity of an entire attack, from launch to grasp

Full textMicro-opto-electro-mecanical systems (MOEMS) are primordial tools for future applications in several scientific fields as telecommunications or image display. Astronomy takes also advantage of their great adaptatbility thanks to the development of adaptative optics; a new spectro-imager called BATMAN has recently been develloped to be installed at Telescopio Nazionale Galileo (TNG) in the Canaries Islands. The control of the MOEMS allowing computerizing this processus has been the starting point of my work at the LAM.The main part of this manuscript deals with another application conceived thanks to the association of the characteristics of MOEMS and photosensitive materials developed at Politecnico di Milano (Italy). These materials can be put in two states differentiated by their transparency. The MOEMS, initially used to display images, allows controlling the dose of light projected on the photocrhomic plate which reacts by becoming more and more transparent. This process permit to record Computer Generated Holograms (CGHs) in grayscale which are used in optical metrology. Today, binary CGHs are used but our process allows to record amplitude quantified CGHs with a resolution of 13.68 µm and a precision better than 1% in term of transparency, even with a non homogeneous illumination beam. Comparative studies have shown advantages of quantified CGHs of Fresnel and Fourier families. Two new Fourier algorithms have been conceived thanks to use of the third dimension offered by the control of the transparency. They have been realized and tested succesfully, and have shown much better performances than the current binary coding, so called Lee algorithm

Full textThis thesis is in the field of frequency metrology. It relates the observation of a bilinear magneto-electric effect in E and B in dilute media, not yet observed at the beginning of this thesis. We are particularly interested in cases where E and B are mutually orthogonal. To detect this effect, we use a high finesse Fabry-Perot ring cavity with 4 mirrors. A beam emitted by an infrared laser is split into two in order to circulate in two counterpropagating directions inside the optical cavity. This cavity contains rods delivering orthogonal electric and magnetic fields to each other and also orthogonal to the propagation vectors of the two intra-cavity beams. The application of E and B changes the resonant frequencies of the optical cavity for the two directions of propagation. This is called magneto-electric directional anisotropy. This effect was first observed in nitrogen gas at atmospheric pressure and in a followinf experiment in a crystal of Er: YAG. Next we modified the original experimental device, by putting it under vacuum in order to measure the effect of magneto-electric directional anisotropy in gases at sub-atmospheric pressures. Moreover, eigen polarization measurements of non-planar optical cavities have also been made to emphasize the importance of these for measuring the effect of magneto-electric directional anisotropy. It was made using bowtie cavities, highly non-planar with negligible birefringence in reflection, and ring cavities, slightly non-planar with a significant birefringence in reflection. These cavities are similar to the ones used for the detection of the magneto-electric effect studied in this thesis

Full textIn this thesis, laser-induced damage phenomenon in fused silica components is investigated in the nanosecond regime. This material is one of the most widely used in optics, particularly on high-energy laser facilities such as the Laser MégaJoule. In order to ensure the nominal operation of this kind of laser facility, laser-induced damage on optical components has to be understood and controlled. This phenomenon consists in an irreversible modification of the material. In the nanosecond regime, laser-induced damage is tightly correlated to the presence of precursor defects which are a consequence of the synthesis and the polishing of the components. The interaction between these precursor defects and the laser pulses strongly depends on the laser characteristics. The first study focuses on the metrology of the laser beam used in laboratory to study laser-induced damage. The second one consists in a parametric study of the initiation mechanism on the rear surface of fused silica components. The last part deals with the influence of nonlinear propagation on laser induced damage on the surface and in the volume of thick fused silica samples
