基于WRP点云三维物体的优化分层研究

Research on Optimal Layering of 3D Objects Based on WRP Point Cloud

空间曲面光源的衍射计算研究中,将曲面光源转换为平面光源的集合是一种较为流行的算法。基于波前记录(WRP)方法,计算出三维物体点与WRP虚拟平面有效距离关系,并通过对不同三维物体进行WRP分层计算,得出三维物体WRP分层计算的最优化分层数。模拟及光电再现实验结果表明,该方法在一定程度上能够加快计算全息图生成速度,并且重建像质量较高。

In the study of diffraction of spatial surface light sources, the way of conversing surface light sources into pla nat light sources is a popular algorithm. Based on the WRP method, the effective distance relationship between the three di mensional object points and the WRP virtual plane was calculated, and the WRP layered calculation of different three dimen sional objects was performed to obtain the optimal layering numbers for the 3D object WRP layering calculation. Simulation and photoreproduction experiments showed that this method can accelerate the generation of computational holograms to a certain extent, and the quality of reconstruction image was high.
