Abstract
A holographic display including a spatial light modulator, and including a position detection and tracking system, such that a viewer's eye positions are tracked, with variable beam deflection to the viewer's eye positions being performed using a microprism array which enables controllable deflection of optical beams.

A holographic display including a spatial light modulator, and including a position detection and tracking system, such that a viewer's eye positions are tracked, with variable beam deflection to the viewer's eye positions being performed using a microprism array which enables controllable deflection of optical beams, in which a phase correction is applied to compensate for phase discontinuities introduced by the prism array in order to compensate for different optical path lengths to the viewer's eye positions.
A method of generating a holographic reconstruction of a three dimensional scene, made up of multiple discrete points, using the holographic display of any previous claim, the display including a light source and an optical system to illuminate the spatial light modulator;
- comprising the step of:
- encoding a hologram on the spatial light modulator.
