Paper Abstract

This paper will present the development of a new driver board for the Texas Instruments DiscoveryTM 3000 Micromirror Device (DMD) chipset being offered by Texas Instruments. A requirement of our current research is to have a real-time digital interface to a reflective spatial light modulator to project patterns based upon images obtained via a camera system. As a result, we developed the DVimageTM spatial light modulator driver board based upon the Texas Instruments DiscoveryTM 3000 chipset. The DVimageTM can be run from any computer through the standard DVI port, can display 8-bit grayscale at 60Hz in real-time and can store 4600 full resolution 1-bit images on the board and display them at a maximum frame rate of 16,300 fps. The board also has programmable sync pins to trigger other systems (e.g. light sources, cameras). An SDK and software examples have been developed to allow for integration into custom applications. This paper will describe the general hardware architecture and software tools along with example applications for this spatial light modulator system.
