description The invention discloses a method for detecting the intorsion of an optical fiber. The method is based on the Jones vector method and the Stokes vector method. The intorsion rate of the optical fiber is obtained by measuring the parameter (img file='703472dest_path_image001.TIF' wi='20' he='26' /) in the Stokes vector after light passes through the optical fiber according to the relation between the change of the polarization state of monochrome polarized light during optical fiber transmission and the intorsion rate of the optical fiber. By means of the method, detection of the intorsion of the optical fiber is realized, a reference basis is provided for screening of low-magnetic-sensitivity optical fibers, and a great help is provided for improving the environmental adaptability of a fiber optic gyroscope.
