Title:
SCANNING DISTANCE MEASURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/053081
Kind Code:
A1
Abstract:
A scanning distance measuring device (1) comprises: a laser light source (101) that emits laser light; a condensing lens (301) that concentrates laser light which has been reflected by a measurement target object (2); a first light-receiving element (411) that detects the laser light which has been concentrated by the condensing lens (301); a second light-receiving element (421) that is disposed at a position apart from the optical axis (302) by a predetermined distance; and a processing circuit (440) that determines whether or not the measurement target object (2) is present in a distance measuring region (3) on the basis of the laser light which has been detected by the second light-receiving element (421).
