Abstract

We present a 3D-ranging camera based on the optical indirect Time-of-Flight technique, suitable for automotive applications. The camera is based on a 64×32-pixel chip, integrating a Single-Photon Avalanche Diode (SPAD) in each pixel, fabricated in an automotive-certified CMOS technology, and on an 808 nm active illuminator, emitting 1.5 W average optical power. Thanks to the SPAD single-photon sensitivity and the in-pixel processing, the camera provides a precision better than 1 m over a 40° × 20° field-of-view, at 45 m distance.
