Abstract

In this paper, we present the main results for the theoretical, numerical and experimental analysis of a new method to measure the roughness of metal surfaces. The requirements for a waveguide optical resonator, which is the main optical node of the device implementing this method, have been developed. A comparative analysis of two different designs of an optical node is performed. The energy spectra of the roughness of various surfaces were measured. As a result of the research, the main advantages of the method under consideration and practical recommendations are provided to improve the design of the device that implements this method.
