Abstract
Coherent image amplification by two-wave coupling in a crystal of photorefractive BaTiO3 is analyzed. This amplifier is optimized with respect to such operational characteristics as gain versus amplified image quality and space-bandwidth product. Experimental results that demon-strate coherent image amplification of 4000, space-bandwidth product of 106, and gray-level dynamic range of greater than 100 are presented.Keywords
