Challenges in DMD™ Assembly and Test

ABSTRACTThe Digital Micromirror Device™ (DMD™) developed at Texas Instruments is a spatial light modulator composed of 500,000 to 1.3 million movable micromachined aluminum mirrors. The DMD™ serves as the engine for the current generation of computer-driven slide and video projectors, and for next generation devices in digital television and movie projectors. The unique architecture and applications of the device present several packaging and test challenges. This paper provides a description of package humidity modeling and verification testing, as well as an overview of the automated optical testing and test equipment that have been developed to support manufacturing of the DMD™.

Test Objects

The possibility of application of a digital micromirror device (DMD) as a spatial light modulator for outputting holographic filters in an optical correlator illuminated by quasimonochromatic spatially incoherent radiation was discussed. The experimental setup of the optical correlator was assembled using a one-lens scheme. Experiments on the recognition of test objects with the synthesized dynamic holographic filters being output onto the DMD were performed. The results obtained allow one to conclude that object recognition can be successfully performed using the proposed scheme of a non-coherent correlator containing a digital micromirror device.

Long Time

Although the digital micromirror device (DMD) has been considered to be a spatial light modulator (SLM) for a long time, it is seldom utilized for holographic tweezers practically because of its energy loss. In this work, a multi-trapping system built with a DMD is demonstrated. But a problem of dispersion is found when the DMD is applied to femtosecond laser, and its mechanism is studied.
