title: Simulation of human vision by image evolution in light-excitable nonlinear optical mediums.
abstract: The nonlinear optical membrane used for image processing was prepared using tetraethyl silicate by sol-gel method under mild conditions. Ru(bpy)3Cl2 (bpy, bipyridine) was immobilized in the sol-gel matrix. This light-excitable membrane containing Ru(bpy)3Cl2 as photocatalyst could catalyze the Belousov-Zhabotinsky reaction by illumination. Our results indicated that a fine-definition image processing could be autoperformed when projecting a picture on this medium. The imaging process was an image evolution process, which was similar to that of the human vision process.
