| Abstract(in English) | We report a depth-resolved imaging technique using a near-infrared laser, where our final destination is to delineate inner structure in turbid media such as biological tissues at a spatial resolution less than 50μm. For this purpose, a scanning confocal imaging system based on optical fiber was preliminarily constructed, which preferentially detects very weak coherent photons, generated in the spatially restricted confocal region and scattered laterally with an incident beam, using the optical heterodyne technique. We show its fundamental imaging properties through experiments using a physical phantom. |
