Abstract

Fiber Bragg Grating(FBG)tensile fatigue property seriously affects the long term reliability of FBG strain sensors.To evaluate FBG tensile fatigue property,the package of FBG sensors is analyzed,and the surface mounting FBG is selected to study the FBG tensile fatigue property.To distinguish the tensile fatigue signal of FBG from the bonding layer,the property of the grating reflection spectrum is proposed as the evaluation index of FBG,and sensing characteristics is proposed as the evaluation index of bonding layer.The grating reflection spectrum evaluation index includes side mode suppression ratio and the 3dB bandwidth.And the sensing characteristics evaluation index includes sensitivity,linearity and the strain transfer efficiency rate.To verify this theory,an experiment based on equal strength beam is conducted,in which the amplitude of"AC"strain is 500micro strains,and the frequency is 18Hz.After 10 million tensile fatigue tests on three FBG sensors,the average bandwidth increase 2.07%,the strain transfer efficiency rate decrease 4.5%,and the sensitivity decrease 3.9%.The experiment results show that this theory is workable.

Abstract

Based on the physical model of which the targets were irradiated through artificial illuminator in normal circumstance,the calculation model of surface temperature was built through building heat conduction differential equations and altering the outedge radiation power.Combing the calculation of surface temperature related to targets′s geographical circumstance and orientation,taking the Hefei building′s eastward surface for example,the surface temperature was simulational calculated and discussed in different irradiation times and illumination parameters.The results show that altering the targets′s outedge namely the targets are irradiated through artificial illuminatorm,the temperature of targets are changed,the degree of variety is determined by illuminator′s power,distance,incident angle,and in general conditions,the surface temperature is changed obviously in the night,but not in the daytime.

Abstract

Implementation of pulsed-pump technique to fiber amplifier is significantly useful in the situation of low repetition rate and high energy pulses operating.The Amplified Spontaneous Emision(ASE) dynamics simulation in a pulsed-pumped ytterbium-doped double-clad fiber amplifier was presented,which provides important references about optimizing the pulsed-pump mode.By solving the rate equations and light power propagation equations in fiber using the finite elements analysis method,the simulations of ASE dynamics were carried out,including evolution of forward,backward ASE power distribution in the fiber and variations of ASE output power at two ends of the fiber in the time span from 0~740 μs after injection of pump light.Through the analysis of simulation results,the difference between forward and backward ASE powers increasing speeds and characteristics of the two kinds of ASE powers distributions dynamic in fiber were indicated.
