ABSTRACT:
Optical apparatus, such as head-up display apparatus, for superimposing visual information on an observer's view of a scene or object comprises a substantially flat transmission hologram through which the observer views the scene or object, the hologram being disposed substantially orthogonally to and midway along an axis between the observer's eye position and projection optics so as to deviate light from an image produced by the projection optics to the observer's eye position with minimal field aberrations.
