Title:
距離測定装置
Document Type and Number:
Japanese Patent JP6775119
Kind Code:
B2
Abstract:
A distance measuring device includes a light emitter (20); a light receiver (30); a protection cover (11) that is located on an optical path between the light emitter (20) and the light receiver (30); a mode switch (46) that switches between a first mode and a second mode; a distance calculator (45) that calculates a distance from a target object based on a difference between a time when light is emitted from the light emitter (20) and a time when reflected light is received by the light receiver (30) in the first mode; and an LD light emission intensity adjuster (42) that adjusts a light emission intensity of the light emitter (20). The adjustment is performed such that a light emission intensity of the light emitter (20) in the second mode is lower than a light emission intensity of the light emitter (20) in the first mode.
