Abstract

A LIDAR according to the technology of the present disclosure includes: a laser light source to oscillate laser light; a beam splitter to split the laser light into two systems; a modulator to modulate a phase of the laser light sent from the beam splitter; a gas cell; a photodetector to detect transmitted laser light having transmitted through the gas cell, and convert the transmitted laser light into an electrical signal; and a wavelength controller to control a wavelength of the laser light source, the laser light source is temperature-controllable, and the LiDAR further includes a target spectrum detector to perform temperature sweep control and constant temperature control on the laser light source.
