摘要
本文利用全息飞光记录的方法实现了全息相干快门超高速摄影。用CPM染料激光器输出的亚皮秒级超短激光脉冲,记录了光波聚焦的动态过程,同时提出了这种新技术分幅频率的计算方法,文中所述实验的分幅频率为10^(12)f/s,达到了目前高速摄影的最高水平。
This paper describes how the method of light- in - flight receding by holography is used to gain ultra- high- speed photography with holography coherence shutters. In the paper the new technique is used to finish the experiment of recording wave front (pulse front) focused by a lens with the CPM dye laser as the light source. The calculating method of the framing frequency of this technique is set forward in the paper, and the framing frequency of the experiment is about 1012 fps, which is the highest level in high - speed photography now.
