System and Method for Autostereoscopic Imaging

A method for making an autostereoscopic display, the method comprising:

• making a holographic optical element 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 by hardening in a formalehyde solution followed by developing with a catechol and urea solution and bleaching in a rehalogenating bleach solution;
• 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.

An autostereoscopic display comprising:

• a motor-controlled rotatable stage;
• a holographic optical element secured for movement with the rotatable stage, the holographic optical element having an eyebox recorded in a single layer panchromatic emulsion exposed to at least three wavelengths of coherent recording light combined in a source beam divided into a reference beam and an object beam to provide a reference to object beam ratio of at least about 2:1 with at least one of the reference and object beams passing through a beam shaping device to substantially uniformly illuminate the holographic optic element during recording;
• at least one illumination source secured for movement with the rotatable stage, the at least one illumination source illuminating the holographic optical element with light corresponding to the at least three wavelengths of recording light from two different horizontal angles to form generally coextensive left-eye and right-eye images within corresponding left-eye and right-eye viewing zones within a predetermined range in front of the holographic optical element;
• a viewer sensor that generates a signal in response to movement of a viewer;
• and
• a controller in communication with the rotatable stage and the viewer sensor, the controller controlling rotation of the stage in response to viewer movement to maintain alignment of the left-eye and right-eye viewing zones with the viewer.
