Integrated optics for astronomical interferometry - I. Concept and astronomical applications
We propose a new instrumental concept for long-baseline optical single-mode interferometry using integrated optics which were developed for telecommunication. Visible and infrared multi-aperture interferometry requires many optical functions (spatial filtering, beam combination, photometric calibration, polarization control) to detect astronomical signals at very high angular resolution. Since ...
متن کاملPlanar Integrated Optics and astronomical interferometry
Integrated optics (IO) is an optical technology that allows to reproduce optical circuits on a planar substrate. Since 1996, we have investigated the potentiality of IO in the framework of astronomical single mode interferometry. We review in this paper the principles of IO, the requirements for interferometry and the corresponding solutions offered by IO, the results of component characterizat...
متن کاملAstronomy and Astrophysics Integrated Optics for Astronomical Interferometry Ii. First Laboratory White-light Interferograms
Your thesaurus codes are: 03(03.09.2) Abstract. We report first white-light interferograms obtained with an integrated optics beam combiner on a glass plate. These results demonstrate the feasability of single-mode interferometric beam combination with integrated optics technology presented and discussed in paper I (Malbet et al. 1999). The demonstration is achieved in laboratory with off-the-s...

متن کاملMEMS Deformable Mirrors for Astronomical Adaptive Optics
We report on the development of high actuator count, micro-electromechanical (MEMS) deformable mirrors designed for high order wavefront correction in ground and space-based astronomical adaptive optics instruments. The design of these polysilicon, surface-micromachined MEMS deformable mirrors builds on technology that has been used extensively to correct for ocular aberrations in retinal imagi...
