Coherent LiDAR with 2D quasi-static MEMS mirror scanning (Invited Paper)

31 January 2023 • 1:50 PM - 2:20 PM PST | Moscone Center, Room 2020 (Level 2 West)

Abstract

Coherent LiDAR concepts for automotive or unmanned aerial vehicle applications are of increasing interest due to their superior performance compared to standard pulse-based systems, especially at longer range. Here, micro-electro-mechanical-system (MEMS) mirrors can be used as a compact scanning device. To merge the advantages of coherent LiDAR technology with the advantages of miniaturized scanning by MEMS mirrors, we present fiber-based frequency modulated continuous wave (FMCW) LiDAR point cloud generation using quasi-static MEMS mirrors. We demonstrate the operation of such a system for the first time, to the best of our knowledge.
