Title:
LIDAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/026147
Kind Code:
A1
Abstract:
A lidar device according to the present invention can comprise: a light source for emitting light of a predetermined wavelength band; a transmission mirror provided on an optical path on which the light of a predetermined wavelength band proceeds, and reflecting the light, to be incident, of a predetermined wavelength band in a predetermined angle range; a reception mirror integrally provided with the transmission mirror and receiving light from an outside; a light detection unit for detecting a transmission/reception time difference or phase difference of the light of a predetermined wavelength band so as to acquire a distance-based 3D image; and a first mirror provided between the light source and the transmission mirror, and reflecting the light received by the reception mirror to the light detection unit. According to the present invention, the transmission mirror and the reception mirror are integrally formed, and a shadow region, which has not been conventionally used, is utilized as a light transmission region such that a separate light transmission space is unnecessary, thereby enabling a minimized design of the lidar device.
