We present an algorithm for generating high-quality holograms for computer generated holography: holographic predictive search. This approach is presented as an alternative to traditional holographic search algorithms such as direct search (DS) and simulated annealing (SA). We first introduce the current search-based methods and then introduce an analytical model of the underlying Fourier elements. This is used to make prescient judgments regarding the next iteration of the algorithm. This approach is developed for the case of phase-modulating devices with phase-sensitive reconstructions. When compared to conventional iterative approaches such as DS and SA on a multiphase device, holographic predictive search offered a fivefold improvement in quality as well as up to a 10-fold improvement in convergence time. This comes at the cost of an increased iteration overhead.

相位全息术的预测搜索算法。

我们提出了一种用于为计算机生成的全息图生成高质量全息图的算法：全息预测搜索。提出了这种方法，以替代传统的全息搜索算法，例如直接搜索（DS）和模拟退火（SA）。我们首先介绍当前基于搜索的方法，然后介绍基础傅里叶元素的分析模型。这用于对算法的下一次迭代做出有先见的判断。这种方法是针对具有相位敏感重构的相位调制设备而开发的。与传统的迭代方法（例如多相设备上的DS和SA）相比，全息预测搜索在质量上提高了5倍，在收敛时间上提高了10倍。
