一种基于微锥形U型光纤-LSPR超高灵敏度的海水盐度传感器
A high-sensitivity seawater salinity sensor based on micro-tapered U-shaped optical fiber and localized surface plasmon resonance
摘要
Abstract
As a key parameter of Earth's water bodies,seawater salinity is crucial for observations in numerous fields.Accurate measurement of seawater salinity is of great significance for maintaining the balance of coastal ecosystems.To this end,a salinity sensor based on the surface plasmon resonance(SPR)effect of microconical U-shaped optical fibers is proposed.The results demonstrate that the sensor achieves ultra-high sensitivity in salinity measurement,along with an excellent linear response,and its detection limit can reach 0.001 13％.关键词
