WebApr 9, 2012 · Abstract and Figures. A new technique for the fast implementation of Brillouin Optical Time Domain Analysis (BOTDA) is proposed and demonstrated, carrying the classical BOTDA method to the dynamic ... WebIn order to both adjust the spatial resolution (SR) and narrow the Brillouin gain spectrum (BGS) linewidth in Brillouin optical time domain analysis system, a novel scheme based on differential pulse pair technique is proposed. By designing the phase and amplitude of the pulse properly, the higher peak gain and narrower linewidth of BGS are ... flannel over sweatshirt boy
