Abstract
A high intensity light modulator includes a micro-mirror light valve target with electrostatically-repelled micro-mirror elements. Each micro-mirror of the target array comprises a base electrode and an overlying micro-mirror element. In operation, charge is deposited upon the micro-mirrors to produce repulsive electrostatic forces that outwardly deflect the micro-mirror elements by an amount proportional to the deposited charge. In one embodiment, an array of micro-mirror light valves is formed directly upon the face plate of a vidicon tube and is addressed using a scanning electron gun.
