不同于菲涅耳衍射，角谱法（ASM）在高数值孔径下计算衍射。然而，这种方法不允许我们在源和目标平面上以不同的采样率进行计算。在这篇文章中，我们提出了一个缩放ASM，它使用非均匀快速傅立叶变换计算源和目标平面上不同采样率下的衍射。(C) 2012美国光学学会
The angular spectrum method (ASM) calculates diffraction calculation in a high numerical aperture, unlike Fresnel diffraction. However, this method does not allow us to calculate at different sampling rates on source and destination planes. In this Letter, we propose a scaled ASM that calculates diffraction at different sampling rates on source and destination planes using the nonuniform fast Fourier transform.
