Abstract:
1. An apparatus comprising: a light source that produces a coherent beam; a beam splitter that splits the coherent beam into an object beam and a reference beam; an object beam optical system for directing the object beam to interfere with the reference beam at a holographic recording material, wherein the object beam optical system includes: a spatial light modulator for intensity modulating the object beam; a collimating lens configured to collimate the object beam; and an aspheric reflector configured to focus the collimated object beam to a location within the holographic recording material, wherein the aspheric reflector is positioned with respect to the holographic recording material so that a focus of the aspheric reflector substantially coincides with the holographic recording material; a reference beam optical system for directing the reference beam to interfere with the object beam at the holographic recording material; and a computer coupled to the spatial light modulator and programmed to control delivery of a rendered image to the spatial light modulator.
