利用矢量积分法，得到了随机电磁光束通过轴对称ABCD光学系统时2×2互谱密度矩阵元素变换的解析公式。我们推导出在任意输出平面z>0的光谱偏振度、光谱相干度和光谱密度的解析表达式。对电磁高斯-谢尔模型光束通过这类光学系统的传输进行了数值计算。
When random electromagnetic beams passing through axially nonsymmetrical ABCD optical systems, the analytical formula for the transformation of the elements of 2×2 cross-spectral density matrix is obtained with the help of vector integration. We derive analytical expressions of the spectral degree of polarization, the spectral degree of coherence, and the spectral density in any output plane z>0. Some numerical calculations are illustrated relating to the electromagnetic Gaussian Schell-model beams propagating through such optical systems.
