Nonlinear optical image processing in photoanisotropic amorphous As(2)S(3) thin film.
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.
