Abstract

Many transient phenomenon with self-luminescence need to be recorded by high-speed photography. In accordance with this special requirement, we have developed the dynamic state adjusting Q-sequential pulse laser in the trajectory research. Photographing with this laser-source, the flying vehicle motion sequential film in different positions can be easily obtained. Changing the light-path a little, two- and three-dimensional outdoor large field-of- view pulse-wave photography can be conducted. According to this sequential film, the two- and three-dimensional signals can be processed conveniently and quantitatively. This paper generalizes the outdoor laser YDS system and laser-moire high-speed photography system, with discussion of the operating principle of this system, placing the emphasis on the analysis of two-stage amplifying sequential-pulse ruby laser dynamic state Q-adjusting technology. The laser parameters are as follows: the laser output interval is even, is a range of 8 - 100 microsecond(s) . It also can be continuously adjusted, the total output energy is 9.8 J, and the maximum repeating frequency is 200 KHz. In the end, it introduced the intermittent pulse laser.
