DarkPulse Technologies

Distributed Fibre Sensing Technologies

DarkPulse presents a BOTDA system based on dark-pulse scattering that provides improved resolution, accuracy, and acquisition time over conventional BOTDA systems, without the severe limitations on sensing length often imposed by other high-resolution techniques. Theoretical validation of the method is given, and experimental results are presented that demonstrate 20-mm resolution strain measurements with an accuracy of ±20 , which is the highest spatial resolution yet reported for a BOTDA system.
