摘　　要：随着光纤技术与传感器技术的快速发展,光纤传感具备高灵敏度、强抗干扰能力、体积小、重量轻、低成本等特点,在测量受伤患者手臂弯曲角度时具有独特优势。同时,光纤传感技术也能够很好地应用在动态角度测量中,有助于解决在医疗康复中角度测量设备体积大、测量精度差、成本高等问题。本文基于光纤传感技术设计了手臂弯曲角度检测教学仿真系统,使用TracePro光学仿真软件建立光纤弯曲模型,采用光纤弯曲代替手臂弯曲,对光纤在不同弯曲角度下光强度变化规律进行仿真,得到总光通量随光纤弯曲角度的变化关系。With the rapid development of fibre optic technology and sensor technology,fibre optic sensing has the characteristics of high sensitivity,strong anti-interference ability,small size,light weight,low cost,etc.,which has a unique advantage in measuring the bending angle of the arm of injured patients.At the same time,fibre optical sensing technology can also be well applied in dynamic angle measurement,which helps to solve the problems of large volume,poor measurement accuracy and high cost of angle measurement equipment in medical rehabilitation.In this paper,based on optical fibre sensing technology,we designed a teaching simulation system for arm bending angle detection,which uses TracePro optical simulation software to establish optical fibre bending model,adopts optical fibre bending instead of arm bending,and simulates the change rule of light intensity under different bending angles of optical fibre,and obtains the change relationship of total luminous flux with the bending angle of optical fibre.
