2015年8月24日 · In this paper, a CMOS image sensor based on avalanche photodiodes (APDs) for time-of-flight optical ranging is presented. In-pixel phase-sensitive detection was obtained thanks to the modulation of APD avalanche gain.

There are two approaches offering promising solutions for high resolution photon counting image sensors. Firstly, CMOS image sensor (CIS) technology with active pixel sensor readout (APS) has been recently employed in DSERN CIS pixels offering <0.30 e …

2020年2月18日 · Panasonic Corporation announced today that it has developed a time-of-flight (TOF) image sensor that uses avalanche photodiode (APD) pixels and is capable of acquiring highly accurate 3D information in accordance with the position of objects from near to far places at distances up to 250 m.

2023年8月24日 · An avalanche photodiode (APD) is a device in which the internal photoelectric effect and the avalanche multiplication effect are exploited to detect and amplify optical signals. An encapsulated APD detector, with an APD device as the core, is the preferred photodetector for lidar due to its high quantum efficiency in the near-infrared waveband.

An APD-CMOS image sensor toward high sensitivity and wide dynamic range Abstract: We present a sensitivity-boosting technique by incorporating an avalanche photodiode into a normal photo-conversion region.
