Streak cameras are widely used in time-resolved two-dimensional (2D) imaging of transient events. According to MarketsandMarkets, the global high-speed imaging market has been valued at approximately US$422M by the end of 2023 with ~8% of an estimated compound annual growth rate from 2017 to 2023. However, existing approaches are strained by long acquisition time, the trade-off between spatial and temporal resolutions, and a reduced field of view. They also require additional components, modification of the streak cameras, and active illumination. Here, we develop compressed ultrafast tomographic imaging (CUTI), which passively records 2D transient events with a standard streak camera. By grafting the concept of computed tomography to the spatiotemporal domain, the operations of temporal shearing and spatiotemporal integration in a streak camera's data acquisition can be equivalently expressed as the spatiotemporal projection of an (x,y,t) datacube from a certain angle. Using a compressed-sensing reconstruction algorithm, the 2D transient event can be accurately recovered in a few measurements. CUTI is used to image the sequential arrival of two spatially modulated ultrashort ultraviolet laser pulses using an image-converter streak camera at 0.5 trillion frames-per-second. CUTI has also been applied to imaging an animation of fast-bouncing balls using a rotating-mirror streak camera at 5 thousand frames-per-second. Exhibiting as a new work mode universally adaptable to most streak cameras, CUTI is envisioned to find many industrial and scientific applications. In this regard, this NSERC I2I Market Study will assist in identifying the most promising applications, analyzing the prospect of the potential market, and facilitating technology transfer from the laboratory to a commercial product.

条纹摄像机被广泛用于瞬态事件的时间分辨二维（2D）成像。根据MarketsandMarkets的数据，到2023年底，全球高速成像市场的价值约为4.22亿美元，估计的复合年度增长率为2017年至2023年。 ，空间和时间分辨率之间的权衡以及降低的视野。他们还需要其他组件，修改条纹摄像机和主动照明。 在这里，我们开发了压缩的超快断层造影成像（CUTI），该成像用标准条纹摄像头被动记录2D瞬态事件。通过将计算机断层扫描的概念接管到时空结构域，在条纹摄像机的数据采集中，时间剪切和时空整合的操作可以等效地表示为从一定角度的（x，y，t）DataCube的时空投影。使用压缩感应重建算法，可以在一些测量中准确恢复2D瞬态事件。 CUTI使用图像连续连接摄影机以0.5万亿帧的每秒为单位，对两个空间调制的紫外线激光脉冲的顺序到达。 Cuti还应用于每秒5,000帧的旋转MIRROR条纹摄像头对快速播放球的动画进行成像。 Cuti被认为是一种新的工作模式，它普遍适用于大多数连续摄像机，因此可以设想找到许多工业和科学应用。在这方面，这项NSERC I2I市场研究将有助于确定最有希望的应用，分析潜在市场的前景，并促进从实验室到商业产品的技术转移。
