Abstract

Pattern formation and self phase conjugation are observed simultaneously in photorefractive potassium niobate. The effects have been modelled assuming the presence of reflection gratings. In this paper, we further the theoretical analysis by incorporating the effects of both reflection and transmission gratings. Also, we state image processing applications of self phase conjugation such as edge enhancement and contrast reversal.
