Abstract

We propose a real-time multi-monitoring interrogation technique based on Fourier domain mode-locked fiber laser for simultaneous measurement of radiation dose and multi-point strain. Radiation dose and multipoint strain can be monitored in real-time by measuring the variation of output power and detection time interval of the sensing signals. Since the operating wavelength of the FDML is continuously controlled as a function of time, it is possible to simultaneously measure the variation of radiation dose and multipoint strain in real time.
