A multi-target multi-degree-of-freedom static and dynamic test apparatus for a distributed sensing optical fiber comprises an optical fiber multi-degree-of-freedom fixing system (70), a manual loading and unloading apparatus (81), an oil pressure control loading and unloading apparatus (40), an optical fiber (80) to be tested, a distributed optical fiber Brillouin frequency shift acquisition system (50), and a data processing and analysis system (60). The optical fiber multi-degree-of-freedom fixing system (70) is sequentially connected to the manual loading and unloading apparatus (81) and the oil pressure control loading and unloading apparatus (40). The optical fiber (80) to be tested is connected to the optical fiber multi-degree-of-freedom fixing system (70) and the distributed optical fiber Brillouin frequency shift acquisition system (50). Performance of an optical fiber is tested by controlling an apparatus in the optical fiber multi-degree-of-freedom fixing system (70). All components of the multi-target multi-degree-of-freedom static and dynamic test apparatus for a distributed sensing optical fiber can be freely assembled and disassembled, a multi-target test platform is built for meeting different test requirements, and a space for secondary development is provided for possible test explorations. The multi-target multi-degree-of-freedom static and dynamic test apparatus for a distributed sensing optical fiber has a variety of advantages: the apparatus has a light structure, is convenient to operate, receives small interference, has multiple test classes, high adaptability and stable performance, and is convenient to load, and the like. Also provided is a test method using the multi-target multi-degree-of-freedom static and dynamic test apparatus for a distributed sensing optical fiber. |
