    • Heterodyne detection for Fiber Bragg Grating sensors 

      Bellil, Hedi; Abushagur, Mustafa (Elsveier - Optics & Laser Technology, 2000-07)
      In this paper, we present a Fiber-Bragg-Grating-based temperature sensor. The technique employs heterodyne detection using two Fiber Bragg Gratings. One of the gratings is used as a reference (local oscillator) and the ...
