Therefore, the optical rangefinder system can reduce production costs. COPYRIGHT KIPO 2018 ...

A LIDAR system is disclosed. The LIDAR system is a 360° LIDAR system without mechanical scanning includes a pulse light output optical source unit; a coupling optical system which connects the optical source to an optical system and can perform beam steering; an ultra-wide-angle illumination optical system using a curved mirror so that the output light can be irradiated at 360 degrees; an ultra-wide-angle light receiving optical system using a curved mirror so as to receive light scattered in all directions; and a detecting unit for detecting the received light, and it is possible to measure all directions using the adjustment of the beam steering without mechanical scanning. Accordingly, the present invention can perform omnidirectional scanning. COPYRIGHT KIPO 2018 ...
