Abstract :
Introducing the work principle of optical fiber sensing technology. Analyze the optical fiber sensing technology monitoring displacement deformation of deep underground by laboratory simulation experiment. Though analyzing the test data, determine the quantitative relationship between optical loss and displacement deformation. The experiment verifies that spiral fiber can increase the dynamic Range of fiber sensing technology to 8.5mm.
