"beam-scanning lidar systems combined with flash lidar 3D... nonmechanical system fits in palm of hand... measures distance of poorly reflective objects such as black metallic cars and automatically tracks motion... dually modulated photonic-crystal laser (DM-PCSEL)light source enable an on-chip all-solid-state 3D lidar system... flash source that can illuminate wide 30°×30° field of view and beam-scanning source that provides spot illumination with 100 narrow laser beams"
