    Abstract: Apparatus (10) is provided for determining the position of a head (17) of a viewer relative to a screen (11) which is illuminated by a plurality of light sources (12a, 12b) to the screen (11) providing a plurality of real images (13a, 13b) displaced one from another and each being associated with a corresponding one of the light sources (12a, 12b). The apparatus (10) includes a detector (16) for detecting light reflected from the object (17) and a computer (15) for determining from which light sources (12a, 12b) the reflected light originates so as to determine signals indicative of location of the object (17) relative to a light field established by the real images (13a, 13b).

    Abstract: Viewing apparatus for providing a viewer with an apparent 3-D image comprises a diffusing holographic optical element (HOE) screen (15), means (17, 19) for illuminating the screen (15) from a plurality of different positions and means (14) for effecting spatial modulation of the light from the respective positions so as to illuminate respective images on the screen (15). The arrangement is such as to provide a plurality of viewing zones (18, 20) whereby each image can be seen only from a corresponding one of the zones (18, 20).

    Abstract: A projection system incorporating a screen (2, 14) with a substantially achromatic response in a direction substantially perpendicular to the plane of the screen. The screen (2, 14) comprises a diffraction grating (4), means (5) for attenuating zero order and a diffuse holographic optical element (6). The system further comprises a focusing element with positive optical power. The aggregate optical power of the grating and the holographic optical element is substantially less than that of the focusing element.
