description: The subject of the graduate qualification work is âMultimode fiber optic interferometer with improved measurement characteristicsâ.
The given work is devoted to a theoretical and practical study, as well as analysis of the amplitude characteristics of multimode fiber interferometer signals and comparison of the results with the results of measurements
This work is a theoretical and practical study, as well as an analysis of the amplitude characteristics of the signals of a multimode fiber interferometer (MFI) and a comparison of the results with the measurement results.
The first section presents a review of the literature on the properties of the MFI signal, the main types of MFI and their operating principles, the application and manifestation of inter-mode interference in multimode optical systems, considers methods for analyzing processes in the MFI, sensors based on the MFI.
The second section is devoted to a theoretical study of the amplitude characteristics of MFI signals. The statistical nature of MFI signals and parasitic differential phase modulation of modes, principles of constructing ACh are considered.
In the third section, methods of averaging MFI signals are considered: averaging over a âlongâ implementation, averaging over an MF ensemble, averaging of signals with laser frequency modulation.
The fourth section is devoted to an expert investigation of MFI with improved characteristics of the output signals. In this section, the scheme of the expert setup is presented, the principles of its operation are described, and the measurement of the sin doused effects on the MFI with the averaging of an FM laser is described.
