Signal to noise ratio in speckle interferometry in the photon counting autocorrelation mode at low light levels
TL;DR: In this paper, an expression for the statistical uncertainty at a point in the summed spatial autocorrelation functions of a finite number of photon limited images is derived for the point-wise signal to noise ratio in speckle interferometry for binary and giant stars.
