The purpose of the Presort Processor is to excise strong narrow band signals from a wideband radar return. It is an optical notch filter based on acoustooptics and fourier transform optics. This latest iteration of this project uses a narrow bandwidth doubled NdYAG laser as an optical carrier and a TIR total internal reflection liquid crystal spatial light modulator to perform the frequency excision.
