压缩超快摄影（CUP）是一种计算成像技术，与短脉冲激光照明同步，实现动态三维成像。通过利用脉冲光被物体反向散射的飞行时间（ToF）信息，ToF- cup可以从单个相机快照中重建体积图像。此外，该方法将深度数据加密与单次快照测量中压缩的3D数据采集结合起来，从而实现高效、安全的数据存储和传输。我们展示了移动物体的高速3D录像，速度高达每秒75卷。ToF-CUP相机被用于跟踪活的彗星金鱼的三维位置。我们还对被散射介质遮蔽的运动物体进行了成像。
Compressed ultrafast photography (CUP), a computational imaging technique, is synchronized with short-pulsed laser illumination to enable dynamic three-dimensional (3D) imaging. By leveraging the time-of-flight (ToF) information of pulsed light backscattered by the object, ToF-CUP can reconstruct a volumetric image from a single camera snapshot. In addition, the approach unites the encryption of depth data with the compressed acquisition of 3D data in a single snapshot measurement, thereby allowing efficient and secure data storage and transmission. We demonstrated high-speed 3D videography of moving objects at up to 75 volumes per second. The ToF-CUP camera was applied to track the 3D position of a live comet goldfish. We have also imaged a moving object obscured by a scattering medium.
