Paper Abstract

Optical digital processor is the core of some future optical parallel computing systems. A novel optical discrete correlation processor using a high-speed digital micromirror device is proposed, which mainly consists of a VanderLugt correlator. In the processor, the computer generated hologram filters which are inputted by the digital micromirror device will determine the specific logical operations. With properties of high reflectivity, high resolution and short response time, the digital micromirror device can control the wave-front of the light beams with high optical efficiency, large contrast ratio and high rate. An experimental prototype is constructed to demonstrate some specific logical operations. The experiment results indicate that, the novel optical digital processor based on digital micromirror device can perform some specific logical operations properly, and the digital micromirror device can remarkably improve the performance of the optical digital processor.
