Design and application on an optical fiber angular displacemen t sensor

利用分叉光纤束和特殊设计的金属温度自补偿旋转杆件作为传感器的核心元件。当受力产生扭转矩 ,驱使杆件敏感变形 ,反射镜系统端面与光纤端面之间产生扭转角位移 ,光通量变化。经后续信号电路系统的技术处理 ,即可获得角位移的线性输出、显示。The key part of sensor made of forking fiber beam and metal revolving rod with temperature self-compensation is specially d esinged.When force is applied, torsion accurred,making the rod to be deformed.An angular displacement takes place between the end face of reflector system and t hat of optic fiber.The light flux also changes.Through the signal handling of af fer end circuit system,the linear output and display of angular displacement can be obtained
