In this paper the polarization state analyzer/generator based on the three-stage polarization controller is developed. The method for determination of input state of polarization based on Muller matrix formalism is proposed. The operation algorithm for regime of generation an arbitrary state of polarization is proposed.
In this paper computer simulation and experimental investigation of the vibration influence on the single-mode optical fiber polarization characteristics was carried out. Measurements were made using a standard optical reflectometer and an external module providing sensitivity to polarization. Based on the obtained data, a measurement algorithm with polarization controller was determined and the method for analyzing the polarization reflectograms was proposed. The possibility of detection and localization of multiple fiber segments under vibration action was demonstrated.
In this paper an application of Raman reflectometry for distributed temperature measurement on overhead power lines was represented. The modification of standard remote fiber test system scheme and requirements to software was proposed. The results of experimental measurements at fiber optical test set and signal processing algorithm was represented.
