FLAMES—High Speed Flash-LiDAR CMOS Imager for Landing Missions
摘要
A high-speed Flash-LiDAR CMOS image sensor which is named FLAMES for landing missions is presented. The sensor features 1280(H) × 1024(V) array size with a pixel pitch of 14 µm. It offers a full-frame capture rate of 500 fps, up to 2000 fps for smaller ROI, such as 500(H) × 500(V). The sensor can operate in 3 different modes, and its time gating sharpness is anticipated to be faster than 5 ns. When correlated double sampling (CDS) is utilized, the readout noise is expected to be less than 10 e-. This paper discusses the architecture of FLAMES sensor, the design considerations employed to achieve high speed and fast time gating and presents relevant simulation results.
