需要能够以高速获取高分辨率数据的成像系统。然而,现代相机捕获的光学信息量受到电子设备数据传输带宽的限制,导致空间和时间分辨率降低。为了克服这个问题,我们开发了连续流压缩高速摄影,它可以记录一个前所未有的空间带宽时间产品的动态场景。通过以时间延迟积分的方式进行压缩成像,我们以200 kHz连续记录了0.85兆像素的视频,对应于每秒170千兆像素的信息流量。
An imaging system capable of acquiring high-resolution data at a high speed is in demand. However, the amount of optical information captured by a modern camera is limited by the data transfer bandwidth of electronics, resulting in a reduced spatial and temporal resolution. To overcome this problem, we developed continuously streaming compressed high-speed photography, which can record a dynamic scene with an unprecedented space-bandwidth-time product. By performing compressed imaging in a time-delay-integration manner, we continuously recorded a 0.85 megapixel video at 200 kHz, corresponding to an information flux of 170 gigapixels per second.
