Error Estimation of BFS Extraction with Optimized Neural Network & Frequency Scanning Range

We present and investigate a scheme for the error estimation formula derivation of Brillouin frequency shift (BFS) extraction based on an optimized neural network and frequency scanning range for a Brillouin optical time-domain analyzer (BOTDA) system. The system uses a general single mode optical fiber as the sensing medium, and the pump pulse duration is much longer than the phonon lifetime to e...
