Abstract
Computer generated Fourier transform matched filters have been constructed using e-beam lithography. These filters were then evaluated by placing them in a VanderLugt optical correlator and addressing them with the original scene used to make the filters. Results show that the spatial frequency content of a filter may be tailored so as to obtain good signal to noise correlations while maintaining high diffraction efficiency.
