摘要：

Based on dynamic strain detection with fiber Bragg gratings, the basic principles of wavelength shift demodulation using matching fiber Bragg gratings are analyzed. The high sensitivity of matching grating demodulation and the advantage of fiber Bragg gratings, which are combined with ultrasonic testing, are innovatively used for studying dependence of the propagation of ultrasonic waves on temperature in the ice. By using the fiber Bragg grating, the relationship between the velocity velocities of the longitudinal wave and shear wave, and temperature of the ice samples are detected. Using Matlab for data processing, the relationship of acoustic parameters with temperature in the ice is obtained, which shows that both the longitudinal wave and the shear wave have an increasing trend with the decrease of temperature. The measured data are also compared with ones measured by ultrasonic system, which demonstrates the accuracy and reliability of the data obtained with the fiber Bragg gratings. Therefore, the present technique can be used to conveniently and proficiently study the acoustic properties of ice. © 2015, Chinese Laser Press. All right reserved.
