It is common to want to correct signals that have been corrupted by wideband dispersion. If the dispersion is caused by a system whose transfer function has a flat amplitude function and a nonlinear phase function, such as is the case with a ltig periodic antenna, the signal can be corrected via a matched filter. In this paper various optical implementations of the matched filter, including one and two dimensional systems, are investigated. The 2D Fourier Filter, along with several simplifications, demonstrating its power, are simulated. The optical implementations of these systems are also discussed. The problem of phase detection of a spatial signal, which arises when dealing with Fourier transforms, is briefly examined and a system capable of measuring said phase is experimentally implemented. Finally a dual Acousto-Optic matched filter is implemented concentrating on the practical aspects the setup. An exhaustive description of the implementation process is presented including experimental results obtained from each step.
