Abstract
The method of the empirical model decomposition and its application to the analysis of data obtained using a laser strain meter is described. The issues of adaptation of the method to the real data are discussed. The method enables identification of a monotone trend and a slow component of deformation process much more efficiently than the conventional techniques. The method shows reliable operation in cleaning of signals from noise and high frequencies.
