Paper Abstract

We describe a compact optic correlator architecture which does not require a CCD camera to input the image to be interrogated. The white light illuminated image can be polarized and imaged directly onto a thin bacteriorhodopsin film which modulates the film's birefringence. Read out of this written information can be achieved using a low power diode or HeNe laser in order to put the image information onto a coherent wavefront. Architectures with the bR film in the input and Fourier plane are considered using performance measures such as the fidelity of feature identification and speed.
