Better HST Point-Spread Functions: Phase Retrieval and Blind Deconvolution

Richard L. White


The accuracy of HST image restorations is often limited by the quality of point-spread functions that are available. Phase retrieval methods are being applied to HST PSFs in an effort to improve the agreement between observed PSFs and PSFs computed using optical modeling programs. The use of blind deconvolution to make better use of observed PSFs is also discussed.
