Simultaneous Strain and Temperature Measurement Using a Superstructure Fiber Bragg Grating

  title={Simultaneous Strain and Temperature Measurement Using a Superstructure Fiber Bragg Grating},
  author={Bai-ou Guan and Hwa-Yaw Tam and Xiao-ming Tao and Xiao-Yi Dong},
A novel and simple fiber-optic sensor based on a superstructure fiber Bragg grating (SFBG) for simultaneous strain and temperature measurement is proposed and demonstrated. The transmission spectrum of the sensor possesses several narrow-band loss peaks situated on the slope of a broad-band loss peak. By measuring the transmitted intensity and wavelength at one of the loss peaks, strain and temperature can be determined simultaneously. The accuracy of the sensor in measuring strain and… CONTINUE READING
