Multi-Tap Time-Resolved CMOS Image Sensors and Their Applications

This paper describes recent progress of multi-tap time-resolved CMOS image sensors and their applications. Using multiple signal taps in each pixel and designing it for high-speed photo carrier response, various CMOS-based highly-time-resolved imaging systems with advanced performance and functions have been developed. Applications include time-of-flight range imaging and biomedical, imaging such as time-resolved near infrared spectroscopy, fluorescence lifetime imaging, simultaneous multiple-focus microscopy and contact-less heart-rate variability measurements.
