Abstract

Noise reduction Optical losses Optimization Photonics Signal to noise ratio Spatial resolution Temperature sensors
Impact of 2D-BM3D parameters on the denoising performance has been fully analyzed for denoising optimization in 100.8km BOTDA. 12.2dB SNR improvement has been achieved without much loss of temperature accuracy and spatial resolution. © 2020 The Author(s)
