A deep knowledge of the fundamental physics phenomena involved in Silicon Detectors is mandatory for their optimal use in dedicated applications. In the present manuscript, this concept is represented for the particular case of two types of Silicon Detectors: (1) the Silicon Photomultipliers (SiPM) and their applications in medical imaging(2)...

The impact on an optical surface by a micrometeoroid gives rise to a specific type of stray light inherent only in the space optical instruments. This causes a double source of light scattering: the impact crater and the ejected contamination. We propose a method of stray light estimation and apply it to the case of the Laser Interferometer...

We describe a setup based on Michelson interferometry for coherent measurements of the backscattered light from a low roughness optical surface under test. Special data processing was developed for the extraction of the useful signal from the various stray contributions to the coherent signal. We achieve coherent detection of light scattered by...
