We proposed a FLCDG based LiDAR system. Innovatively, the proposed FLCDG enables LiDAR as a fast one-shot capturing system (>50k frames/s) and detects the translational as well as the rotational movement. Furthermore, low fabrication cost and lightweight make this device perfectly suitable modern LiDARs, particularly for short distance.
