PHASE-SHIFT AS A BASIS OF IMAGE-PROCESSING IN OSCILLATING CHEMICAL MEDIUM

It was recently shown that a thin layer of oscillating photosensitive version of Belousov-Zhabotinsky reaction can serve a novel model of pa rallel image processing. We study both experimentally and computationa lly the mechanism involved in the image processing by the photosensiti ve oscillating chemical reaction. We propose a scheme for some operati ons of image processing in a network of locally connected oscillators, based on phase shift of oscillations. We also propose an improved che mical description for photo-inhibition of the ruthenium-catalyzed vers ion of the Belousov-Zhabotinsky reaction.
