Abstract:
1. An apparatus for recording holographic stereograms, comprising: a pulsed light source that produces a coherent beam; a material holder holding a holographic recording material; a material holder translation system operable to position the material holder holding the holographic recording material; a beam splitter that splits the coherent beam into an object beam and a reference beam; an object beam optical system, including a spatial light modulator for intensity modulating the object beam, for directing the object beam to interfere with the reference beam at 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, wherein the computer is coupled to the material holder translation system and is further programmed to generate a timing signal used both for timing a positioning of the material holder translation system and for timing a delivery of the rendered image to the spatial light modulator, and the timing signal is comprised in a signal that delivers the rendered image to the spatial light modulator.
