论文摘要
提出了一种可控制的能量法，该方法考虑了传输函数的不足采样问题和源信号的有效光谱能量，以实现近距离和远场的角光谱衍射计算。提出的方法提供了优化的频率边界$ f_ {ce} $，其中它始终保持可控制的能量以衍射。可控的能角光谱方法可显着减少样品的数量，同时具有与以前的角光谱方法相同的精度，这意味着更高的计算效率。分析光谱能的新观点被证明可以改善相关衍射计算的性能。
A controllable energy method, which considers the undersampling issue of the transfer function and valid spectral energy of a source signal, is proposed to implement angular spectrum diffraction calculation in near and far fields. The proposed method provides an optimized frequency boundary $f_{CE}$ within which it always keeps controllable energy to be diffracted. The controllable energy angular spectrum method significantly reduces the number of samples while having the same accuracy as previous angular spectrum methods, implying a higher calculation efficiency. The new perspective of analyzing spectral energy is shown to improve the performance of relevant diffraction calculations.
