Anisoplanatic Imaging through Turbulence
Abstract
The activities in Year 2 have followed two main research directions: The development of a new point-spread function (PSF) reconstruction approach which aims at extracting, from multi-frame observations, a number of PSFs at several locations within an image of an arbitrary object (without point sources). The development of a marginal blind deconvolution estimator, combined with constraints on the observed object such as positivity, for identification of long-exposure adaptive optics PSFs. This approach can also be extended to the anisoplanatic case by its application in different locations of the field of view as a first building block of a global shift-variant image restoration approach. The approaches are complementary to each other. From the first approach it is possible to extract a model for the object's power spectral density that can be used to complete the parameters to be used in the second approach.
