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.

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.

“…So in this paper we apply the diffraction gratings to propagating tsunami wave. It is known that there are set of effective waveguide methods for reflection, deflection and splitting of the propagated waves based on the diffraction grating mechanisms, see for example in optics [3]. An attemp to apply the analogous approach for tsunami wave will be described below, taking into account the set of certain periodical actions in the direction of wave propagation.…”

The main idea of proposed method is based on the novel possibility to create a precise point action of explosion series which produces the diffraction grating. In practice this process could be achieved by bombarding the ocean with explosive material in vicinity of tsunami region from the earth or from airplane. The tsunami velocity could be decreased and the wave front could be disturbed. In this paper the relevant calculations were performed for this overall process to be optimized.
