Abstract
A holographic display and more particularly an apparatus and method for a curved electro-holographic display are disclosed. The apparatus mainly includes at least one light source for providing lights, at least one axially symmetric mirror for reflecting the lights coming from the light source, at least one spatial light modulation system having one or more than one spatial light modulators for modulating the lights reflecting from the axially symmetric mirror and forming a desired optical reconstruction above the axially symmetric mirror by reflecting the lights which is seen from a viewing zone by the user.
Claims34
An apparatus for holographic display comprising:
- at least one light source for providing a source light beam
- and characterized by
- at least one axially symmetric convex mirror for reflecting the source light beam and configured to shape the source light beam so that the source light beam propagates radially over the entire radial range for axially symmetric illumination, and
- a spatial light modulation system being hit by the light beam which has been reflected by the axially symmetric convex mirror and has propagated for axially symmetric illumination, having one or more than one spatial light modulators for modulating light reflecting from the axially symmetric convex mirror and forming a desired optical reconstruction above the axially symmetric convex mirror, wherein the one or more than one spatial light modulators of the spatial light modulation system are in a configuration that has a central axis, and wherein the central axis is substantially collinear with the axis of symmetry of the axially symmetric convex mirror.
