摘要
提出一种利用CCD测量液体折射率的简单方法。当一束激光斜入射到一个充满液体的长方形样品池时 ,透射光线将产生一定量的偏移 ,利用CCD自动测量这一偏移量 ,就可以很快地计算出该液体的折射率。采用He -Ne激光测量了纯水、乙醇和丙酮的折射率。
A simple method for measuring the refractive index of liquid using CCD is presented.When a laser beam impinges obliquely on a rectangular cell filled with liquid and passes through the cell,the propagation axis of the transmitted beam is displaced from that of the incident beam.By measuring automatically the displacement using CCD,we can determine the refractive index of the liquid quickly.Beams of a He-Ne laser is used for measuring the refractive indices of pure water,ethanol and acetone.
