摘要：
We propose and demonstrate an all solid-state light detection and ranging (Lidar) system based on lens assisted beam steering (LABS) technology. A frequency modulated continuous wave (FMCW) coaxial Lidar system at 1550 nm with 16 scanning directions, 0.35 degrees beam steering step and 1.05 degrees total steering angle is demonstrated. The function of beam steering and 3D imaging are demonstrated. In FMCW ranging experiments, the Lidar system is measured to have 210 m ranging capability. The ranging accuracy can be further improved by applying phase noise compensation. This work proves the potential application of a new integrated beam steering technology in Lidar and demonstrates the way for a fully integrated Lidar system.
