液体折射率双线 CCD 的动态测量

摘要

设计了液体折射率双线CCD的动态测量系统，采用尖劈状容器，利用激光垂直入射某一表面，从而实现在工作面固定入射角（等于尖劈状容器的内部顶角），再采用双CCD测量出射光线的角度，从而计算出液体的折射率。此装置结构简单、调整方便，可动态更换待测的液体，实现实时动态检测折射率。%According to the conventional measurement method of liquid refractive index ,w hich u-sually adopt fixed incident angle or refractive angle ,measure the another angle with some methods , and then calculate the liquid refractive index ,a system of double CCD was designed for the real-time dynamic measurement of liquid refractive index .T his system had the advantages of simple principle , convenient adjustment and real-time detection .
