An extendable large aperture phased array mirror system includes a plurality of mirror segments cooperatively configured to receive an incoming electromagnetic beam. In response to signals from a sensor indicative of wavefront distortion in the beam, a control apparatus displaces a plurality of segment actuators to configure the mirror segments to generate an outgoing conjugate phase electromagnetic beam.

An active optical element receiving an electormagnetic beam, comprising: a plurality of optical segments each having opposed front and rear primary surfaces bounded by a plurality of edges formed by intersection with respective secondary side surfaces, said segments being arranged to collectively receive an electromagnetic beam at said first primary surfaces; a plurality of displacement actuators each responsive to control signals affixed to said rear surfaces of said segments to effect linear movement of each segment along a segment axis substantially perpendicular to said front primary surface of its segment and tilting movement relative to said segment axis; a sensor means for providing signals indicative of the relative positions of said front surfaces of said segments; and control means for providing said actuator control signals in dependence on said sensor signals and command signals that are capable of positioning said segments in real time so that said front surfaces thereof collectively form a surface having an arbitrary geometry.
