A 2×32 range-finding sensor array with pixel-inherent suppression of ambient light up to 120klx

Abstract

Real-time 3D imaging has reached a state of development where several fields of application are possible, such as factory automation, consumer electronics, security, and robotics. The first commercial products have already been launched, or will be available soon. Accuracies in the centimeter range or even below, low cost, and robustness to disturbances in realistic indoor and outdoor environments are the key performance demands for these sensors, which are mostly based on the time-of-flight (TOF) principle either in pulsed or continuous- wave (CW) mode.
