本文介绍一种使用线阵ＣＣＤ进行玻璃管内液位测量的光电测量头。与其他ＣＣＤ尺寸测量的光学系统不同，本文依据不同的液体具有不同的折射率，提出利用柱形容器中液体的聚光特性，得到两种不同液体的分界面在线阵ＣＣＤ上清晰的像。
This article describes a use of linear CCD glass tube liquid level measurement of optical measuring head. Different from the optical system of other CCD size measurement, based on the different refractive index of different liquids, this paper proposes the use of the condensing characteristics of the liquid in the cylindrical container to obtain clear images of the interface of two different liquids on a linear CCD.
