title = "Fast and distributed Brillouin time domain analysis of optical fibers",
abstract = "We present two recently developed new methods for fast and distributed strain/temperature sensing in optical fibers, based on Brillouin optical time domain analysis (BOTDA). Both methods make use of very fast (<1ns) and controlled tuning of the optical frequency of a light wave. In the Fast BOTDA (F-BOTDA) method the complete Brillouin gain spectrum is scanned, while in the Slope-Assisted technique (SA-BOTDA) only a single frequency point on the slope of the Brillouin gain spectrum is probed. A sensing speed of a few hundred Hz is experimentally demonstrated, limited only by the fiber length and the need for averaging.",
