The only independent variable in electronic computing is time. Optical computing on the other hand, has inherently two degrees of freedom, the two variables that define a point in a plane. Optical systems always process information in parallel. Such a simple optical element as a lens is capable of performing such a difficult task as a Fourier transform. Therefore, when it comes to pattern classification, optical computing is an attractive option. The Phase Only Filter has been showed to be a powerful tool for tracking objects in a two-dimensional plane. In this research, a special tracking...
