Abstract

A distance measuring light projecting module comprises a light receiving module for receiving a reflected distance measuring light and a background light, a distance measuring unit for receiving the reflected distance measuring light and performs a distance measurement, an image pickup module for receiving the background light and for acquiring a background image, an optical axis deflector for integrally deflecting an optical axis of the distance measuring light and an optical axis of the background light, and an arithmetic control module for controlling the optical axis deflector, wherein the optical axis deflector has a rotary driving module for rotating a pair of disk prisms individually, and a projecting direction detecting module for detecting a rotation angle of each of the disk prisms.
