点火药爆轰场和起始燃烧过程的时间序列干涉法显示

本文利用脉冲YAG激光引燃点火药产生爆轰场和燃烧场,用时间序列干涉法来获得爆轰场和燃烧的时间序列干涉图。其中时间序列干涉法是由大口径长程干涉仪,序列脉冲激光光源和旋转直角棱镜扫描式高速摄影仪组成。这些时间序列干涉图是进一步研究点火药爆轰场和燃烧场特性的基础。

Visualization of explosive field and initial combustion of detonating powder by time series interferometry

A pulsed YAG laser is used to ignite detonating powder to produce a explosive field and combustion field.The time series interferograms of the explosive field and initial combustion process are obtained with a time series interferometry which consists of a large aperture and long path interferometer,a series pulsed laser source and a rotating right angle prism type of high speed canning camera. These time series interferograms form the basis of studying the characteristics of the explosive field and combustion field of the detonating powder.
