Scientific paper

Adaptive optics have become indispensable elements of high-performance optical systems that image through the atmosphere, compensating for image degradation caused by atmospheric turbulence. A typical system includes a wavefront sensor, a deformable mirror consisting of a reflective membrane backed by precision actuators, and support hardware and software. The sensor detects errors in the incoming wavefront; the computer quantifies these errors and commands the actuators to distort the deformable mirror to induce an equal and opposite wavefront error in near real time. The author describes how precision actuators improve imaging capabilities of ground-base monitoring systems and telescopes by distorting deformable mirrors to compensate for atmospheric turbulence.
