Abstract
A system for presenting a head-up display to the operator of a vehicle is disclosed. This system comprises a light source fiber optic bundle (52) which is secured to the helmet of the vehicle operator and generates a light beam signal which travels at an angle proportional to the orientation of the pilot's head and, accordingly, his line-of-sight. This beam is detected by a detector (68) which is optically coupled to the light beam and provides line-of-sight information at its ouput. A computer (96) receives the line-of-sight information together with other information and sends it via a cathode ray tube (112) and an optical coupler (14) to a beamsplitter (16) which provides that information to the operator of the vehicle while allowing the operator to see through the beamsplitter (16), thus providing the operator with additional information without obstructing his view.
