1A2-E01 Image Detector by Head-Scanning Mechanism for Near-Infrared Endoscope(Non-contact Sensing)

Abstract

Recent years, the bioimaging using near-infrared (NIR) over 1000 nm wavelength is attracting attention. By using NIR, it is possible to observe arteries and veins under the skin. Because, NIR has high penetrating into a living body. Existed endoscope using Si-CCD camera can't capture over 1000 nm wavelength. There is Indium Gallium Arsenide (InGaAs) camera capturing NIR light, but it is still so large that can't be downsized for mounting endoscope. In this study, we propose Head-Scanning Mechanism consisted of MEMS mirror and photodetector for endoscope in place of Si-CCD camera and test image scanning by NIR. The experimental results suggest that the proposed method is useful for observe of in vivo deeply.
