Abstract:
A method of improving measurement speed of distributed optical fiber sensors by adopting orthogonal signals and the system thereof is disclosed, which is related to the optical fiber sensor field and solves the problems that conventional technology will increasing the bandwidth of the received signal, reducing the signal-to-noise ratio of the received signal or distortion the spatial resolution of the system. The method comprises steps of generating N periodic orthogonal optical pulse sequence; injecting the N periodic orthogonal optical pulse sequence into the optical fiber under test( 5 ); collecting the scattered light signal; demodulating the scattered light signal with the local oscillating light and then converting into digital signals; extracting the scatter information of the orthogonal optical pulses from the collected digital signals; and arranging the scattered information in order of precedence of the infusion. The measurement speed of the distributed optical fiber sensors is improved by N−1 times.

Claim (Index 8):
A system of improving a measurement speed of distributed optical fiber sensors by adopting orthogonal signals, comprising:\n a signal generating unit for a periodic orthogonal optical pulse sequence; a signal optical path detection unit for injecting the periodic orthogonal optical pulse signal sequence into an optical fiber under test ( 5 ) in order of precedence, collecting scattered light signals, demodulating with the local oscillating light and a scattered light, and then converting the signals after demodulation into digital signals; and a signal processing unit for extracting scatter information of each of orthogonal optical pulses respectively from collected digital signals and sorting sensing information contained in demodulated two signals according to an order of the orthogonal signals injected into the optical fiber under test.
