Suppressing anisoplanatism effects in speckle interferometry.

STELZER C. and RUDER H.

Abstract (from CDS):

The effect of anisoplanatism in speckle interferometry is studied with emphasis on the autocorrelation function and Knox-Thompson data. We introduce a method for eliminating anisoplanatism artefacts by statistical analysis of Fourier amplitudes calculated from Knox-Thompson data. With this method, it is possible to suppress anisoplanatism artefacts nearly completely.
