Computing wave propagation is of the utmost importance in computational optics, especially three-dimensional optical imaging and computer-generated hologram. The angular spectrum method, based on fast Fourier transforms, is one of the efficient approaches; however, it induces sampling issues. We report a Hybrid Taylor Rayleigh-Sommerfeld diffraction (HTRSD) that achieves more accurate and faster wave propagation than the widely used angular spectrum method.
计算波传播在计算光学中至关重要，尤其是在三维光学成像和计算机生成全息图方面。基于快速傅里叶变换的角谱方法是有效的方法之一；然而，它会引发采样问题。我们报告了一种混合泰勒瑞利 - 索末菲衍射（HTRSD）方法，该方法比广泛使用的角谱方法能实现更准确、更快的波传播。
