| Abstract: | In order to reduce the cost, realize the high stability, the high accuracy wavelength demodulation, one kind novel, based on the High Birefringence Fiber loop mirror filter＇s optical fiber sensing system was designed. According to the traditional matrix optics principle, theoretical model was established, the High Birefringence Fiber loop mirror＇s filter characteristic was studied, and the High Birefringence Fiber loop mirror filter＇s demodulation principle was analyzed. After the sensing examination confirmation, this demodulation system to the temperature resolution is 0.05℃, the linearity reaches 0.9986, the experimental result and the theoretical analysis tallies, these demonstrate this system has the good stability, simple structure, high precision and low price, and it is easy to use. |
