Temperature Sensing Using Frequency Beating Technique From Single-Longitudinal Mode Fiber Laser

In this paper, a high-resolution fiber temperature sensor is proposed and demonstrated using the frequency beating technique. The sensor uses a constant wavelength (CW) at 1539.96 nm as the reference signal for the frequency beating technique. The sensor signal is provided by a fiber Bragg grating (...
