Abstract

In recent years, with the rapid development of sensor technology, the design and application of high-precision temperature and salinity sensors have become the forefront of sensor research, in order to effectively improve the sensitivity of sensors, based on the additive manufacturing process, the Fabry-Perot microcavity is fabricated in the fiber end face, and the sensor is designed based on the dual-beam interference principle. In this study, two polymer microcavities of similar sizes were innovatively used to achieve the optical vernier effect. Experimental results showed that the vernier effect increased the temperature sensitivity by about 23.9 times and the salinity sensitivity by about 15.9 times. The long-term stability of the interference spectrum, the salinity sensing capability of low temperature crosstalk, and the low-cost repeatable manufacturing process plan reflect the great potential of the proposed sensor for environmental detection applications.

基于双光子聚合3D打印的游标效应聚合物法布里-珀罗传感系统的高灵敏度温度和盐度传感

近年来，随着传感器技术的快速发展，高精度温度和盐度传感器的设计和应用成为传感器研究的前沿，为了有效提高传感器的灵敏度，基于增材制造工艺，在光纤端面制造了Fabry-Perot微腔，基于双光束干涉原理设计了传感器。在这项研究中，创新地使用了两个尺寸相近的聚合物微腔来实现光学游标效果。实验结果表明，游标效应使温度敏感性提高约23.9倍，盐度敏感性提高约15.9倍。干扰光谱的长期稳定性、低温串扰的盐度传感能力以及低成本的可重复制造工艺计划反映了该传感器在环境检测应用中的巨大潜力。
