A novel, all-optical joint transform correlator using bacteriorhodopsin (bR) spatial light modulators is presented. This architecture employs relatively inexpensive white light sources and He-Ne lasers to exploit the photoinduced anisotropic properties of the bacteriorhodopsin films. Due to the high spatial resolution of bacteriorhodopsin films, the system offers the possibility of being reduced to a compact size. Advantages and limitations of the system are described and comparisons to previously reported optical correlators using bR films are discussed. The authors believe that this is the first time an all bacteriorhodopsin based optical correlator is reported.
