Range and Velocity Measurement with a Bi-static LiDAR System Based on Optical Phased Array

Based on a linearly-chirped DFB laser and two multi-layered Si 3 N 4 -On-Si optical phased arrays, bi-static frequency-modulated-continuous-wave (FMCW) ranging and velocimetry are demonstrated at a ranging resolution of 8 mm and a velocity resolution of 1.6 mm/s.
