Abstract

The synthesis of spherical computer-generated holograms is investigated. To deal with the staggering calculation times required to synthesize the hologram, a fast calculation method for approximating the hologram distribution is proposed. In this method, the diffraction integral is approximated as a convolution integral, allowing computation using the fast-Fourier-transform algorithm. The principles of the fast calculation method, the error in the approximation, and results from simulations are presented.

摘要

研究了球形计算机生成全息图的合成。为了处理合成全息图所需的惊人计算时间，提出了一种用于近似全息图分布的快速计算方法。在该方法中，衍射积分被近似为卷积积分，从而可以使用快速傅里叶变换算法进行计算。介绍了快速计算方法的原理、近似中的误差以及模拟结果。
