ABSTRACT:
Active laser mirror systems and methods for achieving near diffraction limited transmission of laser radiation by actively controlling a reflective surface are disclosed. The apparatus involved in the active mirror system includes a mirror having a deformable surface, a plurality of actuators attached at preselected locations to the nonreflecting side of the mirror, a control assembly for performing logic and providing drive signals to the actuators and a sensor system. The method of achieving the improved transmission includes setting the contour of a deformable reflective surface in accordance with predetermined data, reflecting the transmitted beam off the surface enroute to the target, optically monitoring the surface to determine operational changes thereon, computing corrective data, and applying appropriate changes to the mirror surface.
