Title:
OPTICAL RANGE-FINDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/126294
Kind Code:
A1
Abstract:
The present invention provides an optical range-finding device. The optical range-finding device (1) comprises: a housing (10) provided with an aperture plane (12); and a plurality of light projection/receiving units (20) that are housed in the housing (10) and that project projection light, which is laser light, and receive reflected light. The plurality of light projection/receiving units (20) are disposed in the housing (10) so that optical paths (23) of the plurality of light projection/receiving units (20) mutually overlap at the position of the aperture plane (12), when viewed from a direction perpendicular to the direction in which the view angle of the entire device is wider than the view angle of one light projection/receiving unit (20) by combining the optical paths (23) of the plurality of light projection/receiving units (20).
