Quasi-Random Errors Model
The Quasi-Random Errors mode of the program combines the features of the Systematic Errors and Random Errors modes. It incorporates the sophisticated mathematical algorithm based on the most advanced ideas of the theory of inverse problems (so-called ideas of the regularization of the inverse problem solution). Quasi-Random Errors mode allows you to take into account a priori information about levels of errors in layer thicknesses. Example: reverse engineering of broadband anti-reflection coating produced with the help of very accurate time monitoring. See the details in our publications.
