ABSTRACT:
An electro-optic targeting system for use with a surface-to-air or air-to-air missile launching system is disclosed. The targeting system provides, in a head-up display type system, the capability of sight observation of a target object and video observation of the target object, including magnified visible and thermal spectrum video, in combination with the display of an aiming mark indicating alignment of the weapon system. The targeting system incorporates a combining glass assembly through which the gunner observes the target object and upon which the video image is displayed. The combining glass includes an optically variable density cell of selectively changeable opacity. When the targeting system is operated in a sight mode, the cell is substantially clear, enabling the gunner to see the aiming mark superimposed on the combining glass with sight observation of the forward scene. When the gunner selects video mode, the cell turns opaque, blocking out the forward scene, and permitting a video signal, normal or magnified, to be reflected off the combing glass towards the gunner. In video mode, the gunner sees a video image of the target with the aiming mark superimposed. The cell automatically changes opacity when the gunner selects sight mode or video mode.
