title: Nonlinear optical image processing in photoanisotropic amorphous As(2)S(3) thin film.
abstract: We report on nonlinear optical image processing, such as image addition and subtraction, using photoinduced anisotropy in amorphous As(2)S(3) thin film and propose a method for contrast reversal and edge enhancement of an image.
