Modified self-deconvolution restoration algorithm for adaptive-optics solar images.
The correction conducted by adaptive optics (AO) is partially due to limitations of the hardware. A postprocessing method, such as blind deconvolution, is used to improve image quality. In this Letter, a modified self-deconvolving data reconstruction algorithm, in which the information recorded by the wavefront sensor in closed-loop status is applied to estimate the deconvolution operator, is proposed for AO image deconvolution. This method is applied in deconvolving solar images captured by a 37-element AO system. The result shows that the method is efficient for improving image quality corrected by AO.
