Description
This presentation will review current and emerging sensing modalities for automotive safety and autonomy. Two main silicon-based sensing technologies will be described: (1) High-dynamic-range (HDR, up to 140 dB) CMOS image sensors (CIS) and (2) Single-photon avalanche diode (SPAD) arrays with >30 % photon detection efficiency (PDE).
Firstly, HDR CIS concepts will be reviewed including control of direct sunlight and bright headlamps. Light flicker mitigation (LFM) and motion artifact compensation requirements will be contrasted with typical HDR CIS design tradeoffs related to secondary sub-pixels (~500 nm pitch) and/or short exposures (<0.1 ms).
Secondly, SPAD arrays for use in direct time-of-flight (dToF) light detection and ranging (LiDAR) will be described. Both short-range (< 50 m) flash LiDAR and long-range (100 m to 300 m) scanning LiDAR approaches will be discussed.
Finally, novel SPAD-based HDR stop-motion sensors with capabilities for both imaging and depth sensing will be presented.
