Holographic image recording using liquid crystal
First Claim
Patent Images
1. A method of constructing a multiplex hologram of two dimensional images displayed on an LCD display, comprising:
- generating a series of two-dimensional images;
displaying successive ones of said images on an LCD display matrix;
providing a holographic plate to be exposed;
directing an object beam of coherent radiation at the LCD display matrix so that the transmitted coherent radiation is incident on the holographic plate;
directing a reference beam of coherent radiation at the holographic plate to produce, in combination with the transmitted object beam, a holographic interference pattern on the plate; and
selectively exposing portions of the plate, through slit apertures in a second LCD display matrix, said portions corresponding to successive ones of the images to form a multiplex hologram on the plate.

Abstract
This invention pertains to holography and particularly to a novel method for producing holographic stereogram images from a sequential series of two dimensional images generated on a liquid crystal display matrix. Further a liquid crystal display matrix is used to generate a vertical slit aperture for the masking of a halographic plate.
