complex amplitude

基本解释

The space frequency distribution on rear focal plane restores to the distribution of complex amplitude on image plane.
后焦面上的频率分布还原成像面上的光场复振幅空间分布。
The expression of complex amplitude is given in reference plane vertical to the optical axis by far-field approximation when the line source and the principal axis are at any angle.
在柱坐标下从微分波动方程出发，推导柱面光波的场分布，并利用远场近似条件导出当线光源与光轴成任意角度时，在垂直光轴方向的参考面上的复振幅表示。
The result can be used in numerical calculation and simulation of diffraction and fractional Fourier transform of input complex amplitude of misaligned single spherical refracting system.
这些结果可用于数值计算和模拟该系统失调时对输入复振幅的衍射和分数傅里叶变换。
