Material Detail
Digital Light Projector
This is a Quicktime animation of a Digital Light Projector. A digital light projector provides the capability to display a video or computer monitor signal on a projection screen. Such a projector stands out by its small size, low weight and rather unique use of MEMS. The internal light path starts with a bright halogen source, which is guided through the color wheel, reflects off the MEMS chip and is projected through the projector lens. A close-up of the color wheel and MEMS chip reveals the internal lens and beamsplitter. The micromirror chip is mounted in a package with a transparent window onto the printed circuit board. An even closer view shows the active element: a large array of little mirrors. Millions of these mirrors, each smaller than 20 micron, are packed onto the micromirror chip.
