INTEGRATED LIGHT TRANSMISSION/RECEPTION OPTICAL SYSTEM MODULE AND SCANNING LIDAR HAVING SAME

WIPO Patent Application WO/2018/124413

A1

The present invention relates to an integrated light transmission/reception optical system module and a scanning lidar having the same, the module simplifying an optical system structure and, at the same time, facilitating the alignment of optical systems since a light transmission optical system and a light reception optical system are integrated. According to the present invention, the integrated light transmission/reception optical system module comprises: a light reception lens receiving, by a light detection unit disposed at the rear thereof, light to be received, formed so as to face the center portion thereof from the circumference thereof, and having an optical path groove of which the front side is exposed; a light source for outputting a pulse laser along the optical path groove so as to allow the same to face the center portion of the light reception lens from the circumference thereof; and a light transmission mirror disposed in the optical path groove, and positioned on a path of the pulse laser so as to reflect, to the front, the pulse laser outputted from the light source.
