Abstract

Phase diversity techniques are robust post-processing tools for image enhancement and correction of telescopic and atmospheric induced aberrations. We present results obtained applying the Partitioned Phase-Diverse Speckle (PPDS) technique to images acquired at THEMIS. We also present an image quality estimator based on image power spectrum content we developed in order to automatically evaluate the results of large amount of data.
