| Abstract: | The outline of the current ultralong distance optical fiber interferometric sensing system development status,the theoretical analysis of the impact of polarization on the optical fiber sensing system,and a variety of factors which can affect the polarization are given.The squeezetype polarization controller based on photoelastic effect is used to tune the extinction ratio of the system by providing radial stress to fiber interferometer arm,to tune system polarization state dynamically,which makes it possib... |
