For any parachute system, it is important to predict the opening forces it will experience in order to make a safe and economic choice of materials to be used. Developed fiber optic sensors on two twisted fibers with the locked ends and variable twisting step have been used for creation of intellectual knots of perspective vehicles, in particular, parachute canopies and slings. We decided to change our measuring procedure from measuring of transmitted power or its Raleigh scattering in different ends of twisted fibers onto Brillouin scattering characterization. For this situation we offered the kind of method of frequency variation to get the information about the frequency shift and Q-factor of the Brillouin scattering in each sensor.

“…A certain progress in systems of characterization of SMBGS was reached by generating the scanning double-band amplitude modulated probing radiation from pumping radiation. However this method is characterized by the low sensitivity, caused by need of reception and processing of signals in a wide bandwidth (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20), and also strong influence on measurement inaccuracy of the upper sideband existence. The solution of this problem also was in use of the double-frequency radiation generated unlike for pumping radiation.…”

“…It is based on use of advantages of single-band modulation and two-frequency probing radiation, which gives possibility of transfer the data signal's spectrum in the low noise region of a photodetector 16,17 . Also this radiation is characterized by effective procedure of processing of received spectral information by envelope's characteristics of beats of two spectral components.…”

This article is presented materials from two tutorials: "Optical two-frequency domain reflectometry 1, 2 " and "Microwave technologies in industry, living systems and telecommunications 3 ". These materials were prepared for master training courses and listed in the "SPIE Optical Education Directory" for 2013/2014. The main its theme is microwave photonics. Microwave photonics has been defined as the study of photonic devices operating at microwave frequencies and their application to microwave and optical systems. Its initial rationale was to use the advantages of photonic technologies to provide functions in microwave systems that are very complex or even impossible to carry out directly in the radiofrequency domain. But microwave photonics is also succeeding in incorporating a variety of techniques used in microwave engineering to improve the performance of photonic communication networks and systems. Three parts of this chapter are devoted to applications and construction principles of systems forming microwave photonic filters, measuring instantaneous frequency of microwave heterodyne signals and characterizing stimulated MandelstamBrillouin scattering spectrum in ROF systems. The main emphasis is on the use of the two-frequency symmetric radiation, generated by the Il'in-Morozov's method 4 , in given systems. It is forming radiation for the synthesis of optical filters coefficients, it's application and processing determine the increase in the signal-to-noise ratio during heterodyne frequencies monitoring and characterization of nonlinear effects spectrum.

The paper addresses principles of construction and ways of analyzing an electrooptical 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 singlemode optical fiber. The purpose is in improvement of the metrological, technical and economic characteristics of electronic-optical systems of this type.
