| Abstract(in English) | PPP-BOTDA (Pulse-PrePump Brillouin Optical Time Domain Analysis) method was published in previous work and the possibility of access with 10cm spatial resolution was illustrated. The system has been applied in various fields using this 10cm spatial resolution and ± 25 με strain measuring precision. This paper reports the result of the theoretical study for the feasible spatial resolution, and the PPP-BOTDA measuring system to realize the theoretical study. This paper also reports the test results of 2cm spatial resolution and ± 25 με strain measuring precision using a prototype of rack-type PPP-BOTDA measuring system thus illustrate that the PPP-BOTDA system is appropriate for the cm-order spatial resolution. |
