• Micro Electro Mechanical Systems– this means small moving devices

• It’s a technology, not an application– MEMS devices can be found in many places

• TI has chosen to concentrate on small moving silicon mirrors

• Analog 3D MEMS– 2 axis, gimbaled mirror– Single mirror for precision pointing– Electro-magnetic actuation

• Analog 2D MEMS– 1 axis, scanning mirror– Mirror designed for scanning applications– Electro-magnetic actuation

• Digital 2D MEMS– “Digital” operation, on/off– >900,000 mirrors on a single die– Electro-static actuation
