Analysis of deformation fields in cross sections of vibration type optical fiber sensors

摘要

In this paper we analyzed and calculated the temperature distributions and deformation fields in the cross section of optical fiber under periodical photo thermal excitation applied to one side of cylindrical surface. This calculations were made to optimize the exposure and to minimize energy, needed for realization of this class of sensors. The main difference from other papers is the non-symmetrical heating for initiating vibrations.
