3D打印光纤压力传感器

Optical fiber pressure sensor by 3D printing

根据光纤弯曲损耗效应,设计了光纤压力传感器,采用3D打印制作主体部件,与光纤、光纤法兰等整合为光纤压力传感器.该传感器具有可变受力、受力限位、可变灵敏度等功能.光时域反射方法测试结果表明:该传感器可应用于分布式光纤传感系统.

Based on optical fiber bending loss effect,the optical fiber pressure sensor was designed.The main parts were the 3 Dprinting,integrating with the optic fiber and the fiber flange.The sensor had many advantages,such as the varying mechanical stress,the stress limit,the varying sensitivity,and so on.The test with the optical time domain reflection indicated that the sensor could be applied to distributed optical fiber sensing system.
