Abstract

The one-step ultragram, a flexible-format computer-graphic holographic stereogram, is demonstrated in full color. Geometric limitations due to parallel diffusion screen and integral exposure planes are discussed. Image processing and translation schemes that allow for multicolor registration are demonstrated. Emphasis is placed on the pre- and post-swelling color techniques used to register color separated, predistorted component images in order to produce full-color reflection-format stereograms. Experiments using a single laser wavelength to produce a one-step white light-viewable image for each component color are presented. The wide view angle afforded by the flexible ultragram recording geometry, combined with a true color technique, is shown to result in a practical hardcopy display of three-dimensional computer-generated scenes.
