Quantitative Analysis of <i>φ</i>-OTDR Spatial Resolution Influenced by NLM Parameters

Quantitative Analysis of <i>φ</i>-OTDR Spatial Resolution Influenced by NLM Parameters

Non-local mean (NLM) can significantly improve the signal-to-noise ratio (SNR), but it inevitably reduces the spatial resolution of distributed optical fiber sensors (DFOS), which hinders its practical application and the improvement of DFOS performance. In this paper, the quantitative relationship...
