Paper Abstract

A series of tests on a speckle imaging camera system using the Knox-Thompson image reconstruction algorithm was performed. For simulated and real point sources the speckle OTF remains above the noise level for spatial frequencies up to 0.8 of diffraction limit. Laboratory measurements of MTF curves using a resolution chart target were also made with and without simulated atmospheric phase aberrations. Even in the presence of aberrations the KT processed images have consistently higher MTF than those without phase aberrations. We also present a method for subtracting power spectra bias applicable to CCD focal planes with finite electronic noise.
