ABSTRACT:
A rotatable head up display system is provided to furnish target coorindate nformation to the pilot of an aircraft, for example. The head up display may be slaved to a FLIR or TV tracker to display the scene viewed thereby as well as the azimuth with respect to the aircraft. A small cathode ray tube is used for the display and the scene is viewed through a holographic lens so that the display appears at infinity focus. The pilot is also provided with means for controlling the aiming of the sensor (FLIR, TV, or the like).
