Zusammenfassung:	A system and method for measurement and correction of aero-optical and aero-thermal effects to an EO/IR sensor's window/dome (102) on a supersonic flight-vehicle. Range-gating of laser pulses measures and separates aerodynamic and atmospheric effects. Separate control algorithms and control loops at different update rates both simplifies the control algorithms and improves overall performance. The use of a MEMS MMA (124) having tip/tilt/piston capabilities as the deformable mirror to provide wavefront correction enhances overall performance. The corrected laser pulses may also be used to actively illuminate a target to provide both active and passive detection.
