摘要

为了获得灵敏度高且温度独立的塑料光纤传感器，采用研磨法制备了D形光纤，对D形区域进行升温-降温循环水浴处理，并将水浴处理后的光纤制备成U形传感器。研究了U形区域的不同直径及曲率对传感器灵敏度的影响，并对比分析了未经温度处理和升温-降温循环水浴处理后的塑料光纤传感器在葡萄糖溶液中对温度的依赖性。研究表明：传感器灵敏度受U区直径和U区弯曲曲率的控制，当U区直径和曲率分别为1 500

m和0.025 mm

-1

时，传感器对葡萄糖溶液（25℃）的灵敏度达到最高0.017/g（100 mL）

；经温度处理后，传感器对观测区域葡萄糖溶液在25℃和65℃输出光强相对变化量的最大相对误差由未经温度处理的140.1%降低至9.7%，说明对塑料光纤进行升温-降温循环水浴处理能显著改善其对温度的依赖性。

Abstract

In order to acquire U-shaped plastic optical fiber sensor with high sensitivity and independent temperature

the grinding method was used to prepare D-shaped optical fiber

then heating-cooling circulating treatment in water bath was implemented to D-shape area. Afterwards the optical fiber was made into U-shape sensor. The influence of U-shape area with different diameters and curvatures on sensor sensitivity was analyzed

as well as the dependence of plastic optical fiber on temperature in glucose solutions with and without the heating-cooling circulating treatment. The results show that the sensor sensitivity is controlled by the diameter and curvature of U-shaped region. The maximum sensitivity of the sensor in glucose solution (25℃) reaches 0.017/g(100 mL)

-1

when U-area diameter and curvature are 1 500

m and 0.025 mm

-1

. In addition

the Maximum Relative Error(MRE) of the Relative Change of Transmitted Light Intensity(RCTLI) of the sensor in glucose solution decreases from 140.1% at 25℃ to 9.7% at 65℃

which indicates that water heating-cooling circulating treatment can relieve the temperature sensitivity of the plastic optical fiber.
