Zusammenfassung:An optical system for a display having a combiner (1) with a non-conformal reflection hologram and in which an intermediate image (II) of a display source is formed at a location in the light path to and spaced from the combiner (1), the system comprising at least one diffractive element (5,7) disposed in the light path between the display source (2) and the intermediate image (II) and arranged to counter, at least partially, the chromatic dispersion of the non-conformal reflection hologram (1).
