ABSTRACT:
A display unit for a head-up display system which includes a periscopic arrangement 21a,b at each side of the exit pupil 19 of an optical projector. This arrangement is effective to direct collimated light to a conventional monocombiner 11, from lateral portions of the display which otherwise would not be received by the observer without head movement. It thereby increases the observer's instantaneous azimuth field of view of the display.
