The DMD™
A DMD™ (Digital Micromirror Device™) is a true digital light modulator which utilises an array of up to 2.3 million moving aluminium mirrors,
with each one representing a pixel in the nal projected image. The outermost micromirrors in the array remain inactive (pond of mirrors)
and are not used in constructing the image.
