One kind of adaptive Brillouin spectrum analysis

The present invention provides an adaptive Brillouin spectrum analysis method, comprising the following steps: Step 101: determining whether the test data is out of range of the optical fiber; Step 102: Fast Brillouin spectrum characteristic calculation base value; Step 103: select the most suitable fitting function; step 104: select the best fitting method, the test data analysis; step 105: the selected secondary fitting method of fitting a function corresponding to the secondary database in replacement of the said test data analysis; step 106: the final fitting of the fitting method selected database function corresponding to the final replacement, the test data analysis. With the above embodiment, computing speed can be realized, high efficiency; Brillouin scattering spectrum analysis of the rapid, accurate, missing dots.
