Abstract

In a display system light from an object (14) is deflected on to a collimator (16) and superimposed on an external view through a combiner (10) from an observing position (11). Relay optics (17) in the path of light from the object (14) has spaced apart elements (L1,L2) which produce first and second exit pupils (P1, P2). Exit pupil volumes (V1, V2) overlap to give an extended field of biocular view. The restricted field of view associated with prior art display systems is overcome since the present system provides a large field of view at the observing position (11), while system components fit within aircraft space constraints, such as windshield (19), fairing (33) and ejection line (20). Space remains available for other instrumentation, such as a second display CRT (45).
