📄 原文摘要

Industries, Hamamatsu, Japan 1 2 Ultra-high-speed cameras are a powerful tool for biology as well as physics and mechanics to analyze the process of ultra-high-speed phenomena. The frame rate of the state-of-the-art burst-readout ultra-high-speed silicon imagers has reached approximately 20Mfps [1,2]. To observe faster phenomena such as plasma generation in laser processing, the state of electrons in a chemical reaction, and so on, much faster cameras are desired. There are several factors that prevent the speed-up of the ultra-high-speed imager: high gate control voltages and high power dissipation for high-efficiency multi-stage charge transfer in CCD imagers, and the current density limit of the power and ground lines and RC-constant of the vertical readout lines in CMOS imagers.
