| 摘 要： | 光纤电容液滴分析仪(FCDA:Fiber-capacitive Drop Analyzer)是一种用于液体特性研究的新型仪器,该仪器利用光纤液滴分析技术和电容液滴分析技术制成特殊的液滴传感器,获取经过液滴的光强信号随液滴生长变化的规律,得到反映液体综合特性的“液滴指纹图”。该仪器具有测量液体的物理特性参数的能力。本文就利用光纤电容液滴分析仪在液体折射率的测量方面进行了研究,利用线性关系来测量不同浓度的酒精的折射率,并给出了结果的误差分析。

| Abstract: | Fiber-Capacitive Drop Analyzer(FCDA), a newly developed instrument to study the property of the liquid, is based on a specially designed drop sensor by means of the fiber drop analyzing technology and the capacitive drop analyzing technology, and produces a volume-based fiber drop trace (VFDT) which shows the relation between the light intensity passing through the liquid drop and the instant drop volume. The instrument has the capability to measure the parameters of the physical properties of the liquid. This paper shows the study on the measurement of the refractive index of the liquid by FCDA. It shows the measurement result of the refractive index of alcohol of different consistence and the error analysis. |
