Simultaneous Measurement of Strain and Temperature Incorporating
a Long-Period Fiber Grating Inscribed on a Polarization-Maintaining Fiber
Abstract—Simultaneous measurement of strain and temperature was demonstrated by using a long-period fiber grating inscribed on a polarization-maintaining fiber (PM-LPG).The spectral sensitivities of the two adjacent resonant dips of the PM-LPG were measured with respect to strain and temperature.The sensitivities of each resonant dip for strain and temperature were different in magnitude and sign,which makes this PM-LPG have a capability of simultaneously sensing strain and temperature.Experimental results show root mean square deviations of 15.6 and 0.7 C for strain and temperature,respectively.Index Terms—Long-period fiber grating (LPG),optical fiber sensor,polarization-maintaining fiber (PMF),strain,temperature.
I.INTRODUCTION
FIBER GRATING sensors have yielded great attention due to their significant advantages such as wavelength domain response,electromagnetic noise immunity,high sensitivity,compactness,simplicity of fabrication,etc.They have been used for health monitoring and spatial analysis of engineering structures.One of the most significant limitations of fiber grating sensors is their dual sensitivity to strain and temperature.Therefore,a great many efforts have been made to discriminate the wavelength shift produced by strain from that produced by temperature [1]–[4],among which are the two fiber Bragg gratings (FBGs) embedded in a glass tube [3] and a single FBG written in an erbium :ytterbium-doped fiber [4].Recently,Chen et al.[5] reported that the FBG written on a high birefringence fiber can be incorporated for the simultaneous measurement of strain and temperature.They simultaneously measured strain and temperature by measuring wavelength shifts of two Bragg wavelengths in the FBG which have different responses to strain and temperature with respect to the two principal input polarizations aligned along the fast and slow axes of the fiber.But the differences between each response of the FBG to strain and temperature at each Bragg wavelength were not so large,which might restrict the accuracy of the sensor.In this letter,we demonstrate simultaneous measurement of the strain and temperature with high accuracy compared with the previous work using FBGs reported in [5],based on a long-period fiber grating (LPG) inscribed on a polarization-maintaining fiber (PMF).To our best knowledge it is the first time the LPG inscribed on the PMF (PM-LPG) is applied for simultaneous sensing of strain and temperature,though the PM-LPG by itself is not a new concept.
