The method provides 1.5 dB signal-to-noise ratio improvement over unipolar Golay with halved measurement time, securing high spatial resolution.Hybrid Coding Scheme for Brillouin Optical Time-domain Analysis Based on Golay and Differential Pulsestext::conference output::conference proceedings::conference paper
