论文摘要
全息预测搜索（HPS）是一种基于搜索的全息图生成的新方法，它使用对光学转换的数学理解来做出明智的优化决策。现有的搜索技术，例如直接搜索（DS）和模拟退火（SA），依赖于试验对测试全息图和观察结果的修改。一个公式用于决定是否应接受更改。 HPS使用对基本数学关系的知识进行了先见之明的操作，以对测试全息图进行确切的更改，以保证该变化的“最佳”结果。在这项工作中，我们扩展了原始研究的范围，以涵盖相位敏感和相位不敏感系统以及菲涅尔和弗劳恩霍夫衍射。在讨论的情况下，在最终错误中观察到高达10倍的改进，该方法还提供了生成时间的显着性能优势。这是以增加复杂性和普遍性丧失为代价的。
Holographic Predictive Search (HPS) is a novel approach to search-based hologram generation that uses a mathematical understanding of the optical transforms to make informed optimisation decisions. Existing search techniques such as Direct Search (DS) and Simulated Annealing (SA) rely on trialling modifications to a test hologram and observing the results. A formula is used to decide whether the change should be accepted. HPS operates presciently, using knowledge of the underlying mathematical relationship to make exact changes to the test hologram that guarantee the 'best' outcome for that change. In this work, we extend the scope of the original research to cover both phase and amplitude modulating Spatial Light Modulators (SLMs), both phase sensitive and phase insensitive systems and both Fresnel and Fraunhofer diffraction. In the cases discussed, improvements of up to 10x are observed in final error and the approach also offers significant performance benefits in generation time. This comes at the expense of increased complexity and loss of generality.
