摘要: The maximum entropy method (MEM) is used to analyze quasielastic light scattering correlation functions. central problem, in such data analysis, the recovery of distribution exponentials describing decay function (i.e., inverting Laplace transform). MEM shown give a high‐quality reconstruction these distributions. success illustrated with results from computer‐generated ‘‘noisy’’ and experimental colloidal dispersions. Both theoretical properties, practical advantages are presented compared current analysis techniques.
