Abstract
We demonstrate two simple yet efficient all-optical image-processing techniques that use nonlinear photosensitive dye-doped nematic liquid-crystal films, namely, edge enhancement and image addition–subtraction operations. These films require no external bias and function at much lower optical powers and shorter response times than other conventional methods.
