The principle of Brillouin optical time domain reflectometer (BOTDR) is introduced and its application to the strain monitoring of the strain distribution of the reinforced concrete beam is studied.
At the same time, it discusses the elements influencing the test accuracy of optical time domain reflectometer (OTDR) and measures for eliminating test error.
同时,还讨论了影响光时域反射仪(OTDR)测试精度的要素和消除测试误差通常采用的对策。
