Phase Difference of Ellipse Polarized Light in Different Frames

本文通过讨论 ,得出了振幅不等的线偏振光迭加形成的椭圆偏振光也可经过坐标旋转变成振幅相等的两线偏振光迭加而成 .分析了两个坐标系下位相差之间的联系 ,并在此基础上得出了椭圆长轴为任意方位时相位差的测量公式 ,并利用几个特例对此结果进行了验证 .

Ellipse polarized light obtained from linear polarized light in different amplitude can also be formed from linear polarized light in equal amplitude through coordinate rotating. The relations between the different reference frames are analyzed and the formula of measuring the phase difference is obtained when the long axis of ellipse is in any orientation in the paper. Several special examples are used to validate the conclusion.
