| Abstract: | We use the Faraday effect to automatically eliminate the impact of random polarization state changes in the arms of a single mode fiber Michelson interferometer for an oral all-fiber optical coherence tomography(OCT)system.Whatever the polarization state changes randomly in both sample arm and reference arm fiber,the intensity of output interference signal always maintains the strongest.The basic principles of the method using the Faraday rotation mirror in all-fiber oral OCT system are introduced,as well a... |
