一种复折射率的测量方法
首发时间:2023-01-05
摘要:通过研究光经过平行吸收介质的折射,获得复折射率实部和虚部与光经过平行吸收介质前后光斑位置的位移量之间的关系。根据函数关系式可知,只需对吸收介质进行两次不同角度的入射,分别测量出光经过平行吸收介质前后光斑位置的位移量,即可计算出吸收介质的复折射率。

Measurement of Complex Refractive Index of Absorbing Medium
Abstract:The light through parallel absorbing medium are studied. We obtained the relationship between the real part and imaginary part of complex refractive index with light spot position displacement when the light before and after through parallel absorbing medium. According to the function equation, it can be calculate the real and imaginary parts of the refractive index of the absorbing medium by measurement the two corresponding light spot position displacement which the light incident parallel absorbing medium before and after with two different angles of incidence.
