| Abstract(in English) | The Pulse-Pre-Pump Brillouin Optical Time Domain Analysis (PPP-BOTDA) method is capable of achieving 2cm spatial resolution. Its fundamentals were already published in our previous papers. The PPP-BOTDA based system has been successfully used in various industrial applications. However, as it was previously pointed out, it was so far able to measure the static or quasi-static strain, only. In this paper, the study on the PPP-BOTDA maximum feasible measurement speed is presented. Moreover, the actual measurements employing developed NEUBRESCOPE NBX-6040A system (1,000 data points, spatial resolution of 10cm and 50με strain uncertainty) at 10Hz frequency (speed) are included. The results clearly demonstrate that PPP-BOTDA based distributed sensing system (NEUBRESCOPE NBX-6040A) is suitable for the dynamic strain measurement. |
