Abstract

Several methods of image reconstruction from turbulently-distorted focal-plane intensity patterns are compared from the viewpoint of noise sensitivity, processing requirements, 4nd ability to deal with extended objects. Computer simulation of the Shift-and-Add method , with and without weighted deconvolution, yields poor results against extended targets. Computer simulation of the speckle interferometry method is carried out as far as correlogram construction; the experimentally meausred noise sensitivity of the phase-retrieval procedure leads to poor predicted image quality. A complete end-to-end simulation of the speckle masking method is shown in detail; the extended target image is reconstructed clearly and unambiguously.
