Abstract
A coherent optical correlator system using the Texas Instruments deformable mirror device (DMD) spatial light modulator as a Fourier plane phase-modulating filter has been constructed and demonstrated. The DMD functions in this system as a electronically addressable phase-only matched filter.1-3 The experimental results obtained using this system agree closely with computer simulations of operational performance based on a model developed for the response characteristics of individual DMD elements. We present here some of the experimental results obtained with the DMD employed as a binary phase-only filter and a comparison of these results to the computer simulation. We also comment on the application of the DMD as an analog phaseonly filter.
