Abstract
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° beam steering step and 1.05° 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.
