摘要

本文研究了利用光电振荡器测量液体折射率的方法。测量原理是基于振荡频率和振荡器的全局环路延迟之间的强关系。对丙酮、乙腈、1,4-二恶烷和1,3-二恶烷的折射率进行了测定。对实验结果进行了讨论，并与文献进行了比较。我们还提出了一种利用外部参考频率源、混频器和频率计数器来实时监测液体折射率的新技术。

A study on measuring refractive index by using an optoelectronic oscillator

This paper presents a study on measuring the refractive index of liquids by using an optoelectronic oscillator. The measurement principle is based on a strong relation between the oscillation frequency and the global loop delay of the oscillator. Several experiments have been implemented to determine the refractive index of acetone, acetonitrile, 1,4-dioxane and 1,3-dioxolane. The experimental results are discussed and compared with previous publications. We also propose a new technique to monitor the refractive index of a liquid in real-time by using an external reference frequency source, a mixer and a frequency counter.
