In this study, we first analyze the fully analytical frequency spectrum solving method based on three-dimensional affine transform. Thus, we establish a new method for combining look-up tables (LUTs) with polygon holography. The proposed method was implemented and proved to be accelerated about twice compared to the existing methods. In addition, principal component analysis was used to compress the LUTs, effectively reducing the required memory without artifacts. Finally, we calculated very complex objects on a graphics processing unit using the proposed method, and the calculation speed was higher than that of existing polygon-based methods.
在本研究中，我们首先分析了基于三维仿射变换的全解析频谱求解方法。因此，我们建立了一种将查找表（LUT）与多边形全息术相结合的新方法。所提出的方法得以实现，并且证明与现有方法相比加速了约两倍。此外，主成分分析被用于压缩查找表，有效减少了所需内存且无伪影。最后，我们使用所提出的方法在图形处理单元上计算非常复杂的物体，并且计算速度高于现有的基于多边形的方法。
