Abstract

Analysis of the shift-and-add (SAA) algorithm in double-star speckle interferometry has been extended to include the case of partial nonisoplanaticity. It was found that the intensity ratio of the ghost to the principal spots produced by SAA is essentially constant, regardless of the degree of nonisoplanaticity, but that the ratio of either outer spot to the center spot declines in a manner similar to that of the autocorrelation.
