Extended Speckle interferometry
Abstract
Speckle interferometry was invented by Labeyrie (1970). The new approach when used in the form of a modification introduced by Liu and Lohmann (1973) makes it possible to obtain high-resolution images of astronomical objects. It is pointed out that the extended Speckle interferometry is very similar to Fourier holography. A description is given of the basic relations of Speckle interferometry, as invented, and of the characteristics of the extended Speckle interferometry.
