description: The subject of the graduate qualification work: âImproving the spatial resolution of optical coherence tomography using methods of parametric spectrum estimationâ. The object of study is the processing of interference signals. The aim is to implement and apply the method of parametric spectrum estimation when processing interference signals of optical coherence tomography (OCT) to improve axial spatial resolution. In this work, an OCT interference signal processing method based on the root-MUSIC algorithm was demonstrated to improve axial spatial resolution. Experimental verification of the effectiveness of the proposed method was carried out by measuring and visualizing the geometric parameters of cross-sections of multimode and single-mode optical fibers. The use of this method opens up the possibility of non-destructive testing of the internal structure of optically integrated components and the geometry of optical fibers required during the production process. Terminological features of the subject area are taken into account and software tools are used to solve problems. Specialized software and mathematics were used MATLAB.
