Abstract
An optical distance measuring device includes a light emitting part, a mirror, a scanner that scans a predetermined scanning range with an irradiation light by operating the mirror in a forward movement motion and a backward movement motion, a light receiving part that detects a reflected light returned by reflecting the irradiation light from a target existing in the scanning range, a distance calculating part that calculates a distance to the target, a timing signal generating part that generates the timing signal according to a signal from an outside of the optical distance measuring device, and a control unit that controls a light emission of the light emitting part and an operation of the scanner. The control unit synchronizes the operation of the scanner with a predetermined timing signal by adjusting a time of one cycle of the scanner while maintaining the distance measuring period of the forward movement motion.
