Abstract
Beam fanning when optimized in photorefractive (PR) crystals, by appropriate selection of wavelength, crystal orientation, and polarization of the input beam, can be utilized to yield edge-enhancement at low input intensities. Exploiting the nonlinear behaviour of beam fanning for different input intensity levels, the higher spatial content is retained in the transmitted beam for spatial frequency information, thus providing real-time edge-enhancement.
