Abstract
The photoinduced dichroism in bacteriorhodopsin films has been investi gated in view of its application for optical Fourier processing. A sim ple optical system for Fourier processing is demonstrated that does no t require precise alignment and vibration isolation. The basic princip le of operation relies on the intensity dependence of photoinduced dic hroism in a bacteriorhodopsin film. Experimental results with Fourier processing are shown for edge enhancement. (C) 1996 Optical Society of America
