Abstract

Based on low-coherence interferometry in standard single-mode fibers, a differential interferometer has been proposed. A twin-reflective mirror demodulator was used in the differential interferometer. This interferometer can be used as a fiber optic sensor to measure the elongation of the fiber or strain substressed on the fiber and has the advantage that it can automatically compensate for temperature-induced variations in the refractive index and thermal expansion of the silica fibers.
