Abstract

The analysis of binary stars has to date been one of the major successes of speckle interferometry. A new technique for estimating the parameters of a binary star is presented. Unlike earlier methods, the system does not require the measurement of a reference star to compensate for the speckle transfer function. The algorithm relies on model fitting to the bispectrum phase and can obtain the separation, position angle, and relative brightness of the two components.
