Abstract

The use of a deformable mirror device (DMD) as an input spatial light modulator and/or as a phase-only spatial filter in a coherent optical correlator is investigated. Both Vander Lugt and joint transform correlator geometries are analyzed, and the results of computer simulations using a simplified phase device model are presented. Detailed geometrical and diffraction models of Texas Instruments' cantilever beam DMD are developed and used to simulate an input phase device in a Vander Lugt correlator. The results are encouraging for those interested in using the DMD for image correlation applications.
