Abstract

A micro-mechanical shutter array using micro-mechanical technology and silicon-on-transparent-substrate technology. The micro-mechanical shutter array is operated by using electro-static forces. Two basic types of shutter movements are described, viz. an electric force/electric counter-force and an electric force/mechanical (spring) counter-force.
