Noise reduction by Brillouin spectrum reassembly in Brillouin optical time domain sensors
Optics and Lasers in Engineering(2020)
摘要
•Spectrum reassembly improves image similarity and decreases size of filter window.•Total processing time decreases due to smaller filter window.•Spatial resolution preserves well due to edge-preserving image filtering strategy.•Measurement accuracy increases by using Brillouin-spectrum-reassembly filter.
