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. Various hologram production system hardware and software designs for use with pulsed lasers can be used with the pre-sensitization techniques.
Claims6
A method comprising:
- providing a holographic recording material;
- pre-sensitizing the holographic recording material by exposing the holographic recording material to an incoherent broadband light source;
- translating the holographic recording material in a first direction, wherein
- the translating the holographic recording material in the first direction is synchronized with delivery of rendered images to be recorded in the holographic recording material;
- 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, wherein
- the exposing is synchronized with delivery of the rendered images to be recorded in the holographic recording material;
- and
- translating the holographic recording material in a second direction, perpendicular to the first direction.
