| Popis: | A fiber-optics multiplexed interferometric current sensor is provided. A broadband light source (BLS) is adapted for providing a light wave, and a depolarizer is coupled to the BLS. A depolarizer and a wave detector are respectively coupled to a first port and a third port of an optical spliter. A passive demodulating interferometric module is coupled between a second port of the optical spliter and a sensor module array. Further, the sensor module array includes an optical coupler coupled to the other port of the passive demodulating interferometric module, multiple leading fibers coupled to the other port of the optical coupler, multiple reflectors, and multiple fiber sensing heads. A port of each fiber sensing head is coupled to the other port of the corresponding leading fiber, and the other port of each fiber sensing head is coupled to a reflector. Each fiber sensing head winds on the corresponding wire. |
