Abstract
An array of electromechanical actuators are positioned beneath a movable mirror and have movable contacts which are affixed to the upper surface of a resistive mat having a single voltage gradient applied across the mat to control the tilting of the mirror. The adjustability of the contact points of each actuator enables the use of actuators which have a substantially varying sensitivity with respect to the application of particular voltages.
