Abstract

A novel, simple low-cost and all-fiber interrogation technique for a strain/temperature fiber Bragg sensor using a long-period grating is demonstrated. The amount of light transmitted by the long-period grating is determined by its wavelength and is therefore proportional to the wavelength of the backreflected light from the fiber Bragg sensor acting as a spectral filter. Over the range 1582-1592 nm, the filter shows a near-linear response of 0.6 dB/nm. This allows an unambiguous sensing range of 10 nm. The additional measurement from the reference arm permits the ratio of the two intensities independent of the optical power fluctuations along the system.
