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).
Claims8
In a visual aid for target acquisition and weapon delivery by an operator from a vehicle, the combination comprising:
- a control arm pivotally mounted to the vehicle above and approximately on the same axis as the head of the operator of the vehicle;
- optical viewing means depending from said arm into the normal field of view of the operator;
- image projection means mounted on said arm in a position to project images onto said optical means;
- movable tracking means on said vehicle for acquiring and tracking a target and trasmitting images to said projection means;
- and
- means automatically positioning said control arm in response to and in coordination with movement of said tracking means to present said projection means substantially along the azimuth of said target.
