Abstract

A deformable mirror assembly is provided employing a pressure differential across the mirror element to flex the mirror into a configuration. The configuration is determined by an array of positioning members, each having a fixed back end and a movable front end. The invention employs long-stroke electromagnet actuators with built-in position sensing.
