The photothermal method for testing of parameters of thin-film coatings

In the given work the high speed photothermal method is offered. In this method a photothermal response in time after the irradiation of sample by one short impulse is registered. For method realization the heat distribution theory in sandwich-type systems is developed and software for the design of thermal response after laser impulse irradiation (with given parameters) on such systems is created.
