Abstract

We discuss the importance of the temporal fluctuation of images viewed through atmospheric turbulence in the determination of their spatial correlation functions. If the basic data is considered to be divided into time-frames, then the temporal characteristics simply determine the exposure or integration time per frame. However, it is more fundamental and better from the point of view of signal-to-noise ratio to treat the data as a set of photon coordinates in space and time. For either approach, the temporal correlation function of the image intensity is of great importance and new measurements of this quantity and its wavelength dependence recorded at La Palma, Canary Islands are given.
