Doppler LIDARs, such as those used in ADAS (advanced driver assistance system) and autonomous vehicles, may need to sense objects at many directions. Some of the Doppler LIDAR devices use mechanically moving parts to scan over a range of directions and the various directions are not sensed simultaneously but sensed in turns over time. Mechanical moving parts generally have higher costs, lower reliability and shorter Mean Time To Failure (MTTF). The LIDAR sensor on chip with Doppler-sensing pixels disclosed herein uses a Doppler sensing-chip that enables Doppler LIDAR devices to sense many directions simultaneously in parallel without having to use mechanical scan and mechanical moving parts, even without having to use electronic scan. Lower costs, higher reliability, and faster detection time as well as higher direction sensing accuracy are objectives of this invention.
