Cameras capable of capturing videos at a trillion frames per second allow to freeze light in motion, a very counterintuitive capability when related to our everyday experience in which light appears to travel instantaneously. By combining this capability with computational imaging techniques, new imaging opportunities emerge such as 3D imaging of scenes that are hidden behind a corner, the study of relativistic distortion effects, imaging through diffusive media and imaging of ultrafast optical processes such as laser ablation, supercontinuum and plasma generation. We provide an overview of the main techniques that have been developed for ultra-high speed photography with a particular focus on 'light-in-flight' imaging, i.e. applications where the key element is the imaging of light itself at frame rates that allow to freeze its motion and therefore extract information that would otherwise be blurred out and lost.

每秒一万亿帧：飞行中光摄影的技术和应用。

能够以每秒 1 万亿帧的速度捕捉视频的相机允许将光冻结在运动中，当与我们的日常体验相关时，光似乎是瞬间传播的，这是一种非常违反直觉的能力。通过将这种能力与计算成像技术相结合，出现了新的成像机会，例如隐藏在角落后面的场景的 3D 成像、相对论畸变效应的研究、通过漫射介质成像以及超快光学过程成像，如激光烧蚀、超连续谱和等离子体生成。我们概述了为超高速摄影开发的主要技术，特别关注“飞行中的光”成像，即
