摘要
实时 ultra-high-speed 渲染来自高比特率干涉图流的数字全息图需要强大的并行计算和高效的数据处理，以实现最小延迟。我们提出了 Holovibes，一个高性能软件引擎，使其能够以前所未有的吞吐量进行实时全息图像重建和短时分析。Holovibes 将空间分 demod 技术（如菲涅尔变换和角谱传播）与时域分析方法（包括短时傅里叶变换 STFT 和主成分分析 PCA）集成于统一的管道中。通过利用基于 CUDA 的 GPU 加速、多线程并行和高效缓冲，系统实现了高吞吐、低延迟的处理，适用于挑战性的计算成像应用。我们演示了在普通硬件上，Holovibes 能够以 71,400 帧/秒的速度从由流式摄像机获取的干涉图进行 sustained 实时全息图渲染，且无丢帧，同时保持 30 毫秒的端到端延迟。该引擎还支持原始或处理数据的同步记录，为必不可少的高速获取工作流程提供支持。该工作在先前的数字全息系统基础上实现了重大突破，为 ultra-high-speed 实时计算成像提供了一个多功能平台。
