Digital micromirror devices have gained popularity in wavefront shaping, offering a high frame rate alternative to liquid crystal spatial light modulators. They are relatively inexpensive, offer high resolution, are easy to operate, and a single device can be used in a broad. A DMD is an optical micro-electrical-mechanical system (MEMS) that contains an array of highly reflective aluminum micromirrors. This document describes how one mirror, or pixel, works. It also explains how rows, blocks, or frames of data can be loaded to an entire DMD array. A DMD is an array composed of multiple high-speed digital light reflectors, consisting of many small aluminum mirrors.
With success of the DMD as a spatial light modulator in the visible regime, the use of DLPTM technology under the constraints of coherent, infrared light for optical networking applications is being explored.
