Simultaneous Measurement of Pressure and Temperature Using a Single Fiber Bragg Grating
A novel sensor based on a single fiber Bragg grating is described. The sensor is configured by encapsulating half of a fiber Bragg grating in a polymer filled metal cylinder and fixing the other half to the metal cylinder. The results show that this sensor is able to measure pressure and temperature simultaneously. Using a novel tactic to transfer the applied pressure to the axial extended-strain on the fiber Bragg grating, the pressure sensitivity reaches 9. 65×10-3MPa-1,which is about 4700 times larger than that of the bare fiber Bragg grating. The accuracy of the pressure measuring can also be improved through introducing a fixed Bragg wavelength as a reference.
