An optical detection system includes: a detecting section which detects position detection information on an object on the basis of a light reception result of reflection light reflected from the object; and a processing section which performs a process on the basis of the position detection information. The processing section performs at least one command process using X coordinate information and Y coordinate information on the object, in a case where it is detected that a Z coordinate range of the object from a target surface is in a first Z coordinate range, and performs a process for a hovering operation using the X coordinate information and Y coordinate information on the object, in a case where it is detected that the Z coordinate range is in a second Z coordinate range which is distant from the target surface compared with the first Z coordinate range.
