摘要
为了获得椭圆率角不变、椭圆方位角可连续变化和椭圆率角可连续变化、椭圆方位角不变的椭圆偏振光,采用矩阵光学方法对按一定方位角摆放的λ/4波片和λ/2波片,在线偏振光通过后的偏振态变化,进行了理论分析和实验验证,取得了可靠的数据。结果表明,理论分析是正确的,这一结果对光路调整和偏振态的转换是有帮助的。
In order to obtain an elliptically polarized light , whose ellipticity angle to be invariable and the elliptical azimuth may continuously change,or the ellipticity angle may continuously change and the elliptical azimuth invariable, the polarization is analyzed based on the matrix optics method when the linearly polarized light transits the λ/4 and λ/2 wave-plates, which are placed according to the certain azimuth ,the reliable data are obtained. The results indicate our theoretical analysis is correct and it is helpful to the path of rays adjustment and the polarization condition transition.
