| Abstract: | Because of the property of the fiber optic sensor to other sensors, we measure strain by mounting the fiber on the surface of the material for material evaluation. In this paper, we develop the relationship of the strain on the fiber and the phase of transmitting light in the fiber when there is pressure on the fiber. We design an interferometric strain sensor taking the advantage of the principle of conventional Mach Zehnder interferometer. |
