WebAdaptive optics (AO) is a technique that removes the atmospheric disturbance and allows a telescope to achieve diffraction-limited imaging from the ground. This is critical in achieving the maximum S/N given in equation (1).The basic idea of AO is to first measure the amount of atmospheric disturbance, then correct for it before the light reaches the camera.
