DLP® Discovery Optics 101 Application Note 2510332 – February 2009

DLP® Discovery System Optics Application Note

DLP® Discovery™

ABSTRACT

This application note describes typical architectures for optical systems employing a single DMD device for projection applications, primarily for small portable projectors. Pros and cons of architectures are discussed in general terms. Front- and rear-screen applications are discussed briefly. Techniques and trades for maximizing critical system performance parameters, defined by the application, are discussed. Unique considerations for DMD devices in optical systems are addressed. A general discussion of image quality and specific design metrics for acceptable performance is included.

Note the majority of this document describes the use of the DMD in a projection optical system, and the DMD is designed with this application in mind. However, there are many other ways to use the DMD to manage and steer light energy. This document addresses some of the non-projection applications briefly, but cannot anticipate all uses.
