| titleOfInvention | Heterodyne interference type fibre optic hydrophone synchronizes electric frame of reference and noise cancellation method |
| abstract | Heterodyne interference type fibre optic hydrophone synchronizes electric frame of reference and noise cancellation method, synchronizing electric frame of reference includes acousto-optic modulator driving, mixting circuit, filter circuit and phase-shift circuit, the electric frame of reference that synchronizes is to be mixed the shift frequency reference signal of two acousto-optic modulators driving, it is obtained after filtering and synchronizes electric reference signal and its orthogonal reference signal, the frequency of the two reference signals is identical as the frequency of the transducing signal of heterodyne interference type fibre optic hydrophone, the shift frequency noise that acousto-optic modulator introducing can be eliminated, improves the performance of fibre optic hydrophone. |
