Abstract

Two joint-transform correlator systems based on deformable-mirror-device (DMD) spatial light modulators and charge-coupled-device (CCD) video cameras are described. The system designs provide for real-time correlation between video-formatted input scenes and stored reference images. The DMD light modulators are used exclusively for inputting data in the optical stages of these systems, and the CCD cameras are used to provide the critical square-law detection required in joint-transform architectures. Experimental verification of the functionality of these DMD/CCD joint-transform systems is also presented.
