ABSTRACT:
An improved multiple channel, wide-angle visual image projection system producing a movable displayed image. The system permits the use of two or more light projectors for high resolution wide-angle image display while eliminating image abutment and alignment problems. The system forms a composite image from two or more projectors in a strategically aligned prism array, the composite image being optically transferred to a single wide-angle projection lens, gimballed in azimuth and elevation, through a pair of movable servo-driven prisms for projection onto a two-dimensional screen. The projection system is especially suited for use in an area-of-interest, helmet-slaved visual display in a flight simulator.
