Source laser pour l’imagerie acousto-optique in vivo et temps réel de milieux diffusants : évaluation, mise en oeuvre
Ce stage a pour objectif de valider un montage laser de combinaison cohérente à quatre amplificateurs optiques, pouvant émettre une puissance crête de 15 Watts en régime quasi-continu (QCW), avec notamment un asservissement repensé. La source sera dans un premier temps évaluée au Laboratoire Charles Fabry (Institut d’Optique), puis transférée à l’Institut Langevin pour des mesures acousto-optiques sur milieux diffusants avec un montage d’holographie numérique et un échographe programmable.
Digital holography for ophthalmology.
The clinical investigation centers of the Quinze-Vingts Eye hospital and The Foundation Adolphe de Rothschild Hospital, and the Langevin Institute in Paris, have developed a unique expertise in the field of innovative computational laser Doppler imaging, optical coherence tomography, and the evaluation of their medical use in a variety of ocular pathologies, which increasingly demonstrates clinical relevance. Monitoring of tissue structure, blood flow, and cell activity in the retina by digital holography will improve understanding of the pathophysiology of visual loss. The digital calculation of the images acquired by optical interferometry is based on a wave propagation algorithm (laser radar- LIDAR), used to reconstruct the image from the data stream sampled by the camera.
