A head-up display system comprising a combiner (5), a projector unit (1, 2, 3) effective to projective light within a selected wavelength band onto the combiner (5), and an element (9) interposed in the light path between the combiner (5) and an observer's viewing position (O). The element (9) is transmissive only to light within the selected wavelength band. This system may be incorporated into goggles or a visor on headgear. <IMAGE> |
