Abstract

ABSTRACT The effect of the temperature on refractive index (RI) sensors based on U and Coil-shaped plastic optical fiber (POF) was investigated. For this purpose, four POF-RI sensor probes were produced, and RI changes caused by ethanol changes in solutions were detected. Two of the produced probes were U-shaped, while the other two were Coil-shaped. For the first time in the literature, the effect of both the geometry of the U and Coil-shaped POF-RI sensors on the sensor parameters and the effect of the medium temperature have been analyzed together. As a result of the experiments conducted at 25°C, the best RI change detection sensitivity, linearity, and resolution values were determined as 821%/RIU, 0.9974 (R2), 5.18 × 10−4. In addition, temperature dependence loss (TDL) and temperature dependence RI deviation (TDR) were measured at different temperatures (25–40°C) in the 1.3346–1.45 RI range, and the effect of temperature change on POF-RI sensor probes was characterized.

温度对U形和线圈形POF传感器折射率变化的影响

研究了温度对基于U形和卷形塑料光纤(POF)的折射率传感器的影响。为此，我们制作了四个POF-RI传感器探针，检测了溶液中乙醇变化引起的RI变化。生产的两个探针是u形的，而另外两个是线圈形的。在文献中首次分析了U型和线圈型POF-RI传感器的几何形状对传感器参数的影响以及介质温度的影响。结果表明，在25°C条件下，最佳的RI变化检测灵敏度、线性度和分辨率分别为821%/RIU、0.9974 (R2)、5.18 × 10−4。此外，在1.3346 ~ 1.45 RI范围内测量了不同温度(25 ~ 40℃)下的温度依赖损耗(TDL)和温度依赖RI偏差(TDR)，表征了温度变化对POF-RI传感器探头的影响。

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
