This paper presents a new application for optical correlation in the form of a head tracking system intended for use in a modern fighter aircraft, where knowing the direction of the pilot's field of view is very important. A video camera, mounted on the pilot's helmet is used to produce a sequence of views of the aircraft cockpit. This view will change from frame to frame as the pilot's head moves and we can use a joint transform optical correlator to track this motion from one frame to the next. In this system, a binary phase joint transform correlator is used to track the frame to frame motion, which can be converted into a change in angle of the pilot's view of the aircraft cockpit. Results from an experimental prototype optical correlation based head tracking system are presented.
