Measurement Accuracy Enhancement via Radio Frequency Filtering in Distributed Brillouin Sensing
In this article, we demonstrate the noise reduction and signal to noise ratio (SNR) enhancement in Brillouin optical time-domain analyzers (BOTDA). The results show that, although the main noise contribution comes from the Brillouin interaction itself, a simple low pass filtering on the detected rad...
