Paper Abstract

We report initial experimental investigation of the Texas Instruments deformable mirror device (DMD) in a joint optical transform correlator. We used the inverted cloverleaf version of the DMD, in which form the DMD is phase-mostly but of limited phase range. Binarized joint Fourier transforms were calculated for similar and dissimilar objects and written onto the DMD. Inverse Fourier transform was done in a diffraction order for which the DMD shows phase-mostly modulation. Matched test objects produced sharp correlation, distinct objects did not. Further studies are warranted and they are outlined.
