1 May 1994 Variable edge enhancement using photorefractive crystals
Author Affiliations +
The use of a low power He-Ne laser (5 mW) and a nonlinear photorefractive crystal is presented in this paper for achieving real time edge enhancement. A Barium titanate crystal is used in the degenerate of four wave mixing mode for obtaining optical phase conjugation.
