Title The generation and propagation of the double
Pulse laser-supported detonation wave in the air
Abstract
The generation and dissemination of the double pulse laser-supported detonation wave in the air are studied in this dissertation in a systematic way. The laser supported detonation wave generation mechanism and propagation mechanisms are also studied. The experimental system of the double pulse laser supported detonation wave generated in the air is also built. The experimental images are collected with the interference method, then processed by Fourier transform and phase unwrapping.The conclusion is obtained through the observation of experimental results.
The optimization of image processing methods is also discussed. The experimental results will provide experimental materials for the double pulse laser detonation wave learning.
