In this article, the locking phenomenon of polarization flipping is reported. A model that integrates the model of the equivalent cavity of a Fabry–Perot interferometer and Lamb’s semiclassical theory is built to explain the locking phenomenon. On the basis of analysis of the model, a method is proposed to release the locking of polarization flipping. After solving the problem of lock-in, the system in this paper can be used to measure small stress of the optical component and phase retardation of the birefringence component.
