Abstract
Pre-sensitization techniques can be used in conjunction with holographic recording materials to allow high quality holographic stereograms to be recorded in those holographic recording materials using pulsed lasers. Additional hologram production system hardware and software designs for use with pulsed lasers are disclosed.
Claims28
A method of recording holograms comprising:
- providing a holographic recording material;
- pre-sensitizing the holographic recording material by exposing the holographic recording material to a plurality of laser pulses;
- and
- exposing the holographic recording material to an interference pattern formed by a reference beam from a pulsed laser and an object beam from the pulsed laser.

An apparatus for recording holographic stereograms, comprising:
- a pulsed light source that produces a coherent beam;
- a material holder holding a pre-sensitized holographic recording material, the pre-sensitized holographic recording material being pre-sensitized by exposing the holographic recording material to a plurality of laser pulses;
- and
- an optical system operable to direct at least a portion of the coherent beam to the holographic recording material, wherein the plurality of laser pulses are provided by at least a portion of the coherent beam.
