基于光纤迈克尔逊干涉仪的食用油折射率的快速测量
Rapid Analysis of Edible-Oil Refractive Index Based on Fiber Optical Michelson Interferometer
摘要: 折射率是反映食用油品质的一项重要指标。为测量食用油的折射率，本文提出了一种新光纤迈克尔逊干涉仪结构，它由经典的双臂光纤迈克尔逊干涉仪和一段玻璃毛细管构成。模拟结果表明，利用该方法能够对食用油折射率进行快速测量，同时具有极高精度，最小分辨率小于0.000001，能为测量食用油品质及地沟油的现场检测提供一种简单有效的手段。
Abstract: Refractive index is an important indicator of edible oil quality. In this paper, we proposed a rapid measurement method for the refractive index of edible oil based on a new fiber Michelson interferometry structure. It combined a glass capillary with the classical dual-arm fiber optical Michelson interferometer. The simulation results confirmed that this method could quickly measure the refractive index of edible oil, and has a high sensitivity. The resolution is lower than 0.000001. This method provides a convenient and effective way for testing edible oil quality.
