SYSTEM AND METHOD FOR AUTOSTEREOSCOPIC IMAGING

摘要

Systems and methods for autostereoscopic display of three-dimensional images include a holographic optical element made by preparing a silver halide gelatin emulsion, coating one side of a glass substrate with the emulsion, holographically recording an eyebox on the coated glass substrate using at least three wavelengths of coherent light combined in a source beam that is divided into a reference beam and object beam with at least one of the reference and object beam passing through a beam shaping device to substantially uniformly illuminate the glass substrate from opposite sides, processing the coated glass substrate, and sealing the coated glass substrate by covering the coated side of the glass substrate with an optical cement and securing to a black glass plate. The element may be mounted in a display and illuminated with at least one projector having optical keystone correction with source wavelengths aligned or matched with the recording wavelengths.
