| Abstract: | 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. |
