Abstract |
| Edge enhancement, a type of intensity filtering of a two-dimensional optical image, was demonstrated using a high-performance photorefractive polymer-dissolved liquid crystal. We calculated the expected images using Fourier transform holographic geometry and obtained good agreement between the observed images and the theoretical expectation. |
