Scientific paper

A generalized formulation of stellar speckle interferometry (SSI) and related techniques in terms of joint spatial/spatial-frequency energy representations are proposed. It is shown how, within this formulation, techniques such as that of Knox-Thompson, or even standard SSI, appear to be particular implementations of a more general method. This generalized SSI is derived in a straightforward manner from the proposed joint formulation. Results from a computer simulation are presented.
