| Zusammenfassung: | The invention discloses an interference demodulation system, which comprises a reference light generating device used for generating reference light, the reference light comprises a light beam which is transmitted on a first axis and is not subjected to frequency shift and a light beam which is transmitted on a second axis and is subjected to frequency shift, the first axis is any one of a fast axis and a slow axis, the second axis is the other one of the fast axis and the slow axis, and the reference light generating device is used for generating the reference light, the interferometer is used for receiving reference light, rotating a light beam, transmitted on a first axis, in the reference light to a second axis for transmission, and rotating a light beam, transmitted on the second axis, in the reference light to the first axis for transmission, so as to generate signal light, the first photoelectric detector is used for detecting interference light signals of the signal light and the reference light, and |
