摘要：
Approximation algorithms of the autocorrelation function of the light scattered by liquid solutions are investigated using a mathematical modeling: a single exponential approximation (for monodisperse medium), the method of cumulants (polydisperse medium) and Levenberg - Marquardt algorithm (two-component medium). The effect of the scattering media and signal parameters (sampling frequency and signal to noise ratio) characteristics on the approximation error is studied in detail. The limits of applicability of the cumulants method and that of Levenberg - Marquardt in correlation spectroscopy are defined. © 2017 by Begell House, Inc.
