抽象。提出了一种低成本、易加工的塑料光纤位移传感器。该传感器采用简单的模压印刷方法制作出具有V型槽结构的宏弯曲塑料光纤，易于实现，有效地降低了制作工艺的复杂度。位移传感采用强度调制法，降低了传感器系统的成本和复杂度。通过实验研究了结构参数对位移传感性能的影响，并通过改变结构参数对所提出的POF探头进行了优化。结果表明，当V型槽结构深度为200 μm，长度为22 mm，角度为60 °，间距为2 mm，POF探针的宏弯曲半径为15 mm时，最高灵敏度可达3.19 × 10 − 2 / mm，测量范围为18 mm。
Abstract. A low cost and easily fabricated plastic optical fiber (POF) displacement sensor is presented. The sensor is based on the macrobending POF with a V-groove structure fabricated by a simple die-press-print method, which is easy to implement and effectively reduces the complexity of the fabrication process. The intensity modulation method is adopted for displacement sensing, which lowers the sensor system’s cost and complexity. Experiments are carried out to investigate the influence of the structural parameters on the displacement sensing performance and the proposed POF probe is optimized by changing the structure parameters. Results showed that when the V-groove structure depth is 200 μm, the length is 22 mm, the angle is 60 deg, the pitch is 2 mm, and the macrobending radius of the POF probe is 15 mm, the highest sensitivity could reach to 3.19 × 10 − 2 / mm with the measurement range of 18 mm.
