Optical Components
 The DMD chip is the central part of this type of projector.
 A DMD chip consists of many small pixel-sized mirrors laid out on a semi-
conductor chip. Light shone on the DMD chip is reflected by all these tiny
mirrors. (For a chip with 1024 x 768 resolution, there are 786,432 small
mirrors.)
 Light is shone onto the chip through a fast-spinning color wheel (CW in
the diagram) that has a red sector, a green sector, and a blue sector.
 This light is reflected off the chip and out through a lens onto a screen.
