IPC: G01S17/46
Filed: 2010-11-18
Abstract: PROBLEM TO BE SOLVED: To provide an optical position detection device and an apparatus with a position detection function capable of preventing leakage of reference light irradiated from a reference light source into a detection light irradiation space, while suppressing detection intensity of the reference light source at a photodetector in a proper level.SOLUTION: An optical position detection device 10 detects a position of a target object Ob based on a light receiving result at a photodetector 30 with respect to part of detection light L3 reflected at the target object, and intensity of reference light Lr incident on the photodetector 30 without passing through a detection target space 10R. The photodetector 30 and a reference light source 12R that irradiates the reference light Lr compose a light-receiving unit 35, which avoids the reference light Lr irradiated from the reference light source 12R from being leaked into the detection target space 10R. The light-receiving unit 35 makes the reference light Lr irradiated from the reference light source 12R incident onto the photodetector 30 with intensity thereof lowered, so that a detection intensity level of the reference light Lr at the photodetector 30 can be suppressed low.
