针对光纤微弯传感器在强扰动信号作用下,因传感光纤弯曲半径小于极限值,致使光纤受损及传感器失效的问题,实验采用自制的短波光固化剂,通过将其封装至已预置有传感光纤的高聚物套管中,利用He-Ne激光器和短波LED分别作为检测和修复光源,研制了一种既能在线自诊断传感器健康状况,同时又能对受损光纤进行实时修复的光纤微弯传感器。实验结果表明:该传感器具有修复时间短、修复效果好等特点。 Aiming at the problem of fiber microbend sensor under strong disturbing signal, the bending radius of sensing fiber is less than the limit value, leading to the problem of fiber damage and sensor failure. The experiment uses self-made short wavelength light curing agent, Sensing fiber in the polymer casing, the use of He-Ne laser and short-wave LED were detected and repaired as a light source, developed a not only online self-diagnostic sensor health, while damaged fiber real-time repair Optical micro-bend sensor. Experimental results show that the sensor has the advantages of short repair time and good repair effect.
