Abstract:
Frequency synthesis-based optical frequency domain reflectometry method and system are disclosed. The method is to implement optical frequency reflectometry and comprises: performing an electro-optic modulation and an acousto-optic modulation on a local light to obtain an optical pulse; inputting the optical pulse as a detection pulse optical signal to a test optical fiber; and detecting an obtained Rayleigh backscattered optical signal under coherent detection with the local light, and then performing a photoelectric conversion and a demodulation, wherein: the electro-optic modulation is performed by using a single frequency signal; the acousto-optic modulation is performed by using a pulse signal; and the optical pulse is obtained by simultaneously sweeping multiple frequency components of an optical comb signal which is obtained by the electro-optic modulation.

Claim (Index 13):
The frequency synthesis-based optical frequency domain reflectometry system according to  claim 8 , wherein:\n the demodulation unit comprises a photoelectric conversion module, a data acquisition card and a demodulation module; the data acquisition card collects electrical signals converted by the photoelectric conversion module, and the demodulation module demodulates the electrical signals.
