摘要
针对海洋水文环境参量实际测量需求,重点介绍了现有各型光纤温盐深仪(CTD)传感器的传感机理、研究进展、性能指标、存在的技术瓶颈等问题,并简要介绍海洋环境参量传感阵列研究进展与工程应用情况。综合国内外研究进展来看,光纤光栅型CTD传感器稳定性和环境适应性较强,已初步满足海洋环境工程监测需求,并且在海洋环境参量传感阵列化研究方面具有重要应用价值;而光纤表面等离子共振(SPR)型CTD和拉锥光纤型CTD灵敏度较高,在海洋环境多参量一体化监测方面具有较大的应用潜力。最后,在简要概述以"海洋物联网"为代表的新一代海洋监测网络发展需求的基础上,对海洋环境参量全光纤传感器发展趋势与技术需求进行展望,以期为从事相关研究的学者提供参考资料与研究思路。
In response to the practical measurement requirements of marine hydrological environmental parameters,this article focuses on the sensing mechanism, research progress, performance indicators, and existing technical bottlenecks of various types of fiber optic ocean conductivity-temperature-depth(CTD) sensors, and also briefly introduces the research progress and engineering application of marine environmental parameter sensor arrays.Judging by the research progress at home and abroad, the fiber Bragg grating CTD sensor has strong stability and environmental adaptability. First, it has initially satisfied the demand of marine environmental engineering monitoring and has had important application value in the research of marine environmental parameter sensing arrays;while fiber-optic surface plasmon resonance(SPR) based CTD and tapered fiber-based CTD have high sensitivity so they have good potential for application in multi-parameter integrated monitoring of the marine environment.Finally, based on the brief description of the development needs of a new generation of marine monitoring networks represented by the "Marine Internet of Things", it proposed the developing trend and technical requirements of alloptical sensors for marine environmental parameters, which will provide scholars engaged in related research with reference materials and ideas.
