A closed loop compensation system including a deformable mirror including an array of spaced actuators. An array of spaced sensors is mapped in optical space to reside between pairs of actuators. A lens system receives a wavefront from the deformable mirror and focuses sub-apertures of the wavefront onto individual ones of the spaced sensors. A sequencer addresses each actuator and associated sensor in the arrays. A compute unit is configured to respond to the sequencer to set a first actuator to an adjusted stroke position and then adjust the stroke of subsequent actuators to locate, to a pre-established position, the focused sub-aperture on a sensor in the pathway between each particular subsequent actuator and a neighboring previously adjusted portion of the mirror to compensate for sub-aperture tilt while maintaining relative phase between sub-apertures.

Closed loop compensation system and method for a deformable mirror

An integrated wavefront correction module including a mounting device a deformable mirror carried by the mounting device for correcting for high spatial and temporal frequency error in an incident wavefront and a tip-tilt correction mechanism including a base and a plurality of tip-tilt actuators interconnected between the base and one of the flexible and fixed portions and a plurality of support posts interconnected between the base and the other of the flexible and fixed portions or alternatively the tip-tilt correction mechanism may include at least one actuator platform, a base, a first set of tip-tilt actuators for adjustably supporting the at least one actuator platform from the base and a second set of tip-tilt actuators for adjustably supporting the mounting device from the at least one actuator platform for adjusting the mounting device and the deformable mirror together to compensate for tip-tilt errors in the incident wavefront with the tip-tilt actuators being operated typically at mid-range in order to define a center of rotation at the mirror surface.
