Abstract

Long range imaging is limited by the optical aberrations produced by the light propagation through the atmosphere. These aberrations will very often limit the angular resolution of the instrument below its theoretical diffraction limit. Various wavefront sensing techniques have been developed over the years to measure the wavefront distortion and correct it. In this paper we investigate the use of phase diversity phase retrieval for the correction of images aberrated by atmospheric turbulence. We describe the implementation of the system and the image correction. We present the reconstruction results and evaluate the performance of the approach for horizontal path imaging with various turbulence strength in the dataset collected during the NATO SET-304 data collection trial.
