Abstract

Since wavefront distortions cannot be directly measured from an astronomical image, a wavefront sensor can use intensity variations from a point source to estimate slope or curvature of a wavefront.  However, processing of measured aberration data from wavefront sensors is computationally intensive, and this is a challenge for real-time image restoration or correction.  In essence, the multi-resolution methods are explored to accurately estimate wavefront distortions from astronomical images of natural source beacons (stars) and to optimise optical wavefront sensor performance.
