Non-mechanical 3D LiDAR system based on flash and beam-scanning dually-modulated photonic-crystal lasers

Abstract

We report a new type of non-mechanical three-dimensional (3D) light detection and ranging (LiDAR) system, which integrates a beam-scanning-type and flash-type dually modulated photonic-crystal laser sources, having a size as small as the palm of the hand. The system is capable of measuring poorly reflective objects in the field of view, overcoming the intrinsic issue affecting conventional flash-type LiDAR systems.
