Abstract EN
To achieve simultaneous measurement of measurand vibration, temperature, and verticality, a three-component fiber Brag grating (TVFBG) vibration sensor is proposed in this paper.
Polymer and metal diaphragm sensitization methods are utilized to improve this sensor measurement sensitivity.
Project matrix theory is adopted to analyze this sensor.
Theoretically, 9×9 nonsingular measuring coefficient matrix of this TVFBG sensor made up by three 3×3 measurand coefficient matrixes is established.
In order to effectively extract measurand, Hilbert-Huang transform (HHT) is accepted to process this sensor’s center wavelength signals.
Calibration experiments are carried out to verify the performance of this TVFBG sensor.
Experiment data confirm that this sensor has excellent frequency response and show good linearity at temperature and verticality measurement.
Wrist rotation angle measurement experiment is also implemented to further identify this sensor practical value.
Through analyzing by HHT, experiment results show that the angle measurement sensitivities of three fiber Brag gratings which are included in this sensor are separately 25.2 pm/°, 38.2 pm/°, and 38.3 pm/°.
