高速摄影目前已被公认为研究快速流逝现象的强有力的工具。而变象管,自从1942年Fnfer第一次在德国应用于单幅高速摄影,到1949年,J.S.Courtney-Pratt在英国用可变的磁场实现了变象管巾象的连续扫描,达到时间分辨率～10~(-9)秒以来,由于变象管高速摄影机,时间分辨率高,操作平稳,易于控制,能使光增强,能进行从红外到紫外的各种不同波段的摄影,允许用高速摄影的各种方法一单幅、多幅、扫描、象分解
High-speed photography is now recognized as a powerful tool for studying the phenomenon of rapidity. The image tube, Fnfer since 1942 for the first time in Germany for a single high-speed photography, to 1949, JSCourtney-Pratt in the United Kingdom with a variable magnetic field to achieve a continuous scanning of the image tube, to achieve time-resolved Since the rate of ~ 10 ~ (-9) seconds, because of the variable speed tube high-speed camera, high temporal resolution, smooth operation, easy to control, can make the light enhanced, can carry out from infrared to ultraviolet in different bands photography, Various methods of high-speed photography a single, multiple, scanning, like decomposition
