Paper Abstract

We report on a definitive demonstration of a 3D holographic display utilizing a photorefractive crystal. The resultant holographic image is viewed in real-time over a wide perspective, which can be extended by a mosaic of crystals. The image is also free from system-induced aberrations and has a uniform high quality over the entire range of FOV angles. The enhanced image quality results from the use of a phase-conjugate read beam generated from a second photorefractive crystal acting as a double-pumped phase- conjugate mirror. Multiple 3D images have been stored in the crystal via wavelength and angle multiplexing.
