论文摘要
我们提出了一种新型算法，用于生成用于计算机产生的全息图的高质量全息图 - 全息搜索。这种方法是作为传统全息搜索算法的替代方法，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，然后引入基础傅立叶元素的分析模型。这用于对算法的下一次迭代做出先见之明的判断。这种新方法是针对具有相位敏感重建的相位调节设备的情况。与传统的迭代方法（例如DS和SA）在多相设备上相比，全息预测搜索的质量可提高5倍，以及收敛时间的10倍改善。这是以迭代开销增加的代价。
We present a novel 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 judgements regarding the next iteration of the algorithm. This new 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 multi-phase device, Holographic Predictive Search offered improvements in quality of 5x as well up to 10x improvements in convergence time. This is at the cost of an increased iteration overhead.
