| 摘 要： | 提出了基于位置敏感器件(PSD)的差动折射率测量方案,建立了数学模型,设计了传感探头结构,制作了原理样机。在反复实验的基础上,测定了盐度标定曲线,并对系统的稳定性和影响因素进行了测量,盐度检测的分辨率达到1.67‰,稳定性好于±1.25‰,温度和扰动引起的误差分别为0.038‰/℃和±2.58‰。对系统误差进行了分析,并提出了相应的解决办法。

| Abstract: | Under the elaborate survey of recent development of the seawater salinity measurement technology,we systematically proposed a measurement principle,based on differential refractive-index and PSD (Position Sensitive Device),and built a mathematical model,designed the structure of sensing probe,produced a prototype.On the basis of numerous experimental data,we determined the salinity calibration curve,the system stability and interfering factors were also measured.Experimental results indicate the salinity re... |
