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.
Claims20
An apparatus for recording holographic stereograms, comprising:
- a pulsed light source that produces a coherent beam, wherein the pulsed light source further comprises an optical parametric oscillator configured to produce at least two substantially different wavelengths;
- a material holder holding a holographic recording material, wherein the holographic recording material is 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 at least a portion of the coherent beam is oriented at an oblique angle with respect to the holographic recording material.
