Enhancing SFDI’s functionality and performance with state-of-the-art CMOS image sensors
Abstract
Recently, new CMOS image sensors with high performance and functionalities such as near-infrared-enhanced global shutter, multi-tap pixels for time-division-multiplexing (TDM) or time-resolved (TR) imaging, and multi-aperture (MA) are emerging. At Shizuoka University, TDM, TR, and MA CMOS image sensors are being developed for LiDAR and biomedical imaging applications. In my talk, examples of SFDI systems with enhanced functionality and performance are shown. (1) multi-wavelength SFDI with suppression of ambient light bias and motion artifacts, (2) fusion of SFDI and near-infrared spectroscopy (NIRS) using scanned multiple lines, (3) fusion of SFDI and time-resolved imaging.
