Abstract
There are many approaches to incoherent imaging through the atmosphere that involve joint estimation of multiple turbulence-induced wavefront-aberration realizations and an object that is common across realizations. These approaches, all of which use short-exposure or “speckle” data, include Multi-Frame Blind Deconvolution (MFBD), Phase-Diverse Speckle (PDS), and Wavelength-Diverse Speckle (WDS). We enumerate fundamental estimation ambiguities that arise within each of these modalities and identify strategies to eliminate some of the ambiguities.
