摘要
液体折射率是表征液体光学特性的重要参数,在许多研究领域对液体的折射率进行直接测量是十分必要的。本文依据全反射定律的物理原理并运用现代传感器技术完成了对透明液体的折射率测量装置的设计与制作,可以实现透明液体折射率的实时测量,相对误差较小,具有成本低、快捷有效等特点,在实验技术等研究领域具有一定的应用价值。
The refractive index of liquid is an important parameter to characterize the optical properties of liquid.It is necessary to measure the refractive index of liquid directly in many research fields.In this paper,according to the law of total reflection principle and modern sensor technology,the design and manufacture of the refractive index of transparent liquid measurement device is presented.It can realize real-time measurement of the refractive index of transparent liquid with small relative error.Besides,it has many characteristics,such as low cost,fast and effective.As a result,it has certain application value in the field of experimental technology and other research fields.
