The paper addresses principles of construction and ways of analyzing an electro-optical probing and characterizing the Brillouin gain contour, based on methods of poly-harmonic probing radiation and evaluation of the parameters by estimating envelopes of its beat frequencies at stages of searching the center frequency, determining the maximum power and width of the contour as basic characteristics of measuring temperature variations and distortion of tension/compression in a single-mode optical fiber. The purpose is in improvement of the metrological, technical and economic characteristics of electronic-optical systems of this type.References
