| Abstract: | An experimental study is performed on the measuring characteristics of BOTDR for structural health monitoring, including dead weight tension test and optical fiber compression-tension test.Based on the experimental results,the effect of optical fiber strain length on measuring results,is analyzed the selection interval for the measuring length of optical fiber strain determined,and the effectiveness of BOTDR for monitoring optical fiber compressive and tensile strains verified. |
| Keywords: | BOTDR optical fiber tensile and compressible strain measuring characteristics |
