摘　　要：通过实验验证马吕斯定律,并分别在消光位置与检偏器和起偏器偏振化方向夹角为45°的位置为检测点测量费尔德常数。通过分析实验数据及理论推导得出在检偏器和起偏器偏振化方向夹角为45°的位置时仪器的灵敏度最好。Malus law is verified by the experiment,and the Verdet constant of the sample is measured by using the points located in extinction optical power and the angle is 45 ° of two polarizer polarized direction.According to the analysis of the result of the experiment and theoretical derivation.The conclusion is that sensitivity is the best when Angle is 45 ° of two polarizer polarized direction.
