Аннотация:The inverse problem of optical coatings control during their deposition is an important practical and industrial problem. The paper presents the mathematical investigation of the layer thickness
errors self-compensation effect that is quite important for the quality production of modern types of thin film optical coatings. It studies the mechanism of thickness errors correlation in the case of direct monitoring of optical coating production by broadband online spectral photometric devices. The mathematical description of this mechanism is provided. The obtained results make it possible to
predict the existence of a strong error self-compensation effect when theoretical optical coating design and parameters of the monitoring procedure are known. Mathematical results of the conducted research are confirmed by computational experiments with the data obtained for the optical coating design problem where a very strong error selfcompensation effect has been practically observed.
