Single-shot ultra-high-speed imaging is of great significance to capture transient phenomena in physics, biology, and chemistry in real time. Existing techniques, however, have a restricted application scope, a low sequence depth, or a limited pixel count. To overcome these limitations, we developed single-shot compressed optical-streaking ultra-high-speed photography (COSUP) with an imaging speed of 1.5 million frames per second, a sequence depth of 500 frames, and an (x,y) pixel count of 0.5 megapixels per frame. COSUP's single-shot ultra-high-speed imaging ability was demonstrated by recording single laser pulses illuminating through transmissive targets and by tracing a fast-moving object. As a universal imaging platform, COSUP is capable of increasing imaging speeds of a wide range of CCD and complementary metal-oxide-semiconductor cameras by four orders of magnitude. We envision COSUP to be applied in widespread applications in biomedicine and materials science.
单次超高速成像对于实时捕获物理、生物和化学中的瞬态现象具有重要意义。然而，现有的技术应用范围有限、序列深度低或像素计数有限。为了克服这些限制，我们开发了单次压缩光学条纹超高速摄影（COSUP），其成像速度为每秒 150 万帧，序列深度为 500 帧，每帧的（x，y）像素计数为 0.5 百万像素。COSUP 的单次超高速成像能力通过记录单个激光脉冲照亮透明目标和跟踪快速移动的物体来演示。作为一个通用的成像平台，COSUP 能够将广泛的 CCD 和互补金属氧化物半导体相机的成像速度提高四个数量级。我们设想 COSUP 将在生物医学和材料科学的广泛应用中得到应用。
