DOPPLER LiDAR APPARATUS USING MULTIPLE WAVELENGTH LASER

Abstract

Disclosed is a Doppler LiDAR apparatus using a plurality of wavelength lasers. The Doppler LiDAR apparatus may include a plurality of light sources each configured to output light for detecting the speed of a target and the directivity of a moving target, an optical system configured to adjust the path or state of light to be output to the outside or reflected light that is reflected by the target, an interferometer configured to make the light that is output by any one of the plurality of light sources and the reflected light that has passed through the optical system interfere with each other, and a detection unit configured to detect information on the distance and speed of the target by receiving the light that has been subjected to interference in the interferometer.

Dependencies are inferred from the claim text.
