Abstract
Optical information processing is a very important branch of optics research nowadays. One interesting application is the comparison of two images. These techniques are of interest in many applications such as automatic inspection, remote sensing or in communication processing. Such a comparison by means of optical methods is a well established technique both for coherent and incoherent illumination and various methods are known. But especially the use of incoherent light is often connected with complex setups. We describe a simple method for a correlation technique based on optically induced anisotropy which allows the use of white light or of two mutually incoherent laser beams. The element based on the specific feature of photoanisotropic media. These materials response on the intensity of a linearly polarized light wave only.
