1152. Reduction of Adaptive Optics Images
... Adaptive optics (AO) now provides superb, diffraction limited images from ground-based telescopes. ... To this effect, a beam-splitter collects part of the corrected wave-front (either from the object itself or from a nearby guide source) and sends it to a wave-front sensor. ... Contrary to noise amplification which affects the deconvolved image more or less uniformly, ringing appears in the vicinity of sharp discontinuities in the object, such as point sources or edge of planetary disks. ...
