Abstract

TI DMD technology can be viewed as a two dimensional diffraction grating. This application note details DMD diffraction, how to achieve blaze conditions, and discover useful formulas. This document examines the two-dimensional diffraction characteristics of DMDs, detailing both the advantages and challenges they present in optical applications.
