Analysis of deformation for optical fibers vibrated-type sensors

Abstract

We analyzed and calculated the deformation based on non symmetrical temperature distributions in the cross section of optical fiber. Deformation distortion causes the micro vibrations of the optical fibers under periodical thermal excitation applied to one side of cylindrical surface. Calculations were made to optimize the exposure and to minimize energy, needed for realization of this class of sensors based on vibrations. The same effect can play negative role for the fiber-optic communication's systems. The main feature in presented work from the similar theoretical considerations is the analysis of the non-symmetrical heating azimuthally with appropriate deformationsKeywords --Optical fibers, vibrated-type sensors deformation analysis.
