Based mzi sensing and long distance collaboration Brillouin sensing, high spatial resolution sensing method

The present invention discloses a sensing and based MZI Brillouin sensing collaboration long distance, high spatial resolution sensing method, is obtained by the first MZI temperature sensor or a strain of the abnormal region, and then measuring the Brillouin sensing range set in the abnormal region is determined by sensing MZI. Incorporating MZI Brillouin sensing and sensing superior performance. Thus, the contradiction can be eliminated binding MZI Brillouin sensing spatial resolution and measurement accuracy. At the same time, each measurement, the measurement range of the Brillouin sensing spatial resolution is determined by the MZI. MZI using the quick response of the sensor, temperature or strain can be determined substantially occurs in the region. The MZI determined temperature or strain sensing abnormal region, the Brillouin measuring range determined in the above-described sensing region, which can greatly improve the measurement rate and spatial resolution of the distributed optical fiber sensing system.
