A biocompatible miniaturized Package housing for a 3D micro mirror based optical Bioprobe for OCT imaging application

摘要

A biocompatible housing for an optical bio-probe is developed for OCT (Optical Coherence Tomography) imaging application. Silicon micro machined 3D mirror is used to steer the optical beam in to the sample of interest. A Grin lens fiber assembly is used to couple the light from the light source to the micro mirror. A Silicon Optical bench (SiOB) is used to integrate the optical components and the 3D mirror. The integrated assembly is housed in a poly carbonate housing with AR (anti reflection) coating on the inner and outer sides of the housing wall. Micro injection molding method is used t o fabricate a miniaturized probe housing which is transparent to 1300nm. Miniaturized housing is tested in an OCT setup and the captured image is processed.
