ABSTRACT:
A display system and method, especially for use in an aircraft head up display system, for maintaining an optical image in a predetermined position on a light emitting screen. The system has a beam type image generator controlled by an operating circuit. A controlled beam scans both a central display region and marginal regions of the screen. The marginal regions have beam sensors and the beam is controlled by a sequence of plural coordinate commands in accordance with a plural coordinate search pattern restricted to the marginal regions and in the vicinity of the beam sensors. Signals resulting therefrom are utilized to eliminate beam deflection errors.
