Key Parameter Extraction for Fiber Brillouin Distributed Sensors Based on the Exact Model

Key Parameter Extraction for Fiber Brillouin Distributed Sensors Based on the Exact Model

Errors in the extracted key parameters directly influence the errors in the temperature and strain measured by fiber Brillouin distributed sensors. Existing key parameter extraction algorithms for Brillouin gain spectra are mainly based on simplified models, therefore, the extracted parameters may h...
