MOMS Lower Power for Digital Light Processors

Digital light processors (DLPs) normally use microelectromechanical systems (MEMS) to control the angle of micromirror arrays. However, for power-sensitive applications such as space exploration, even the microamps required to tilt micromirrors make use of DLPs prohibitive. A University of Delaware engineering professor claims to have solved the problem using micro-optomechanical systems (MOMS). MOMS use lasers to actuate tiny mirror-tipped cantilevers instead of electrical current to power pnematic, piezoelectric or electrostatic actuators. The University of Delaware has received a provisional patent for the technique.
