Abstract

While dead time corrections of single interval photon counting statistics received extensive attention in the literature (some references are given in [1,2]), similar calculations for even the simplest case of double interval statistics - photon correlation functions - were sparse and covered lowest order approximations [3] or rather special cases of clipped correlograms [4] only. The rapidly growing use of photon correlation techniques for velocimetry and, especially, for particle sizing or diffusion measurements in chemistry and biology, however, calls for a proper treatment of dead time effects, in order to increase the dynamic range of quasi elastic light scattering experiments towards higher count rates [5].
