请问老师,我这段代码是不是可以获得正确的圆偏振光相位
S_pol = getresult("grating_s_parameters","S_polarization");
S22_pol = S_pol.S22_Gn;
Es = S22_pol(:,1);
Ep = S22_pol(:,2);
ER = (Ep+1i*Es)/2;
EL = (Ep-1i*Es)/2;
Phase_ER = angle(ER);
Phase_EL = angle(EL);

这个是理论问题啊。你这样应该不能,因为你用两个线偏光只是组成了圆偏光,你改变光源位置或者监视器位置,这种算法的位相就有可能变化,但是它们的位相差应该不变,因为根据定义,圆偏光的共同位相已经踢出去了。 你试一下。
你需要分清“绝对位相”和相对位相。
