摘要
用脉冲激光同轴全息技术建立了全息照相系统和高精度同步时序系统,获得了采用爆轰加载产生高速运动的微射流全息图,并再现出微射流的全息像,得到粒子的大小和分布情况,从图像处理得到粒子尺寸的统计结果表明,最大尺寸在300μm左右,最小尺寸在30μm左右。证明了研制的全息系统和测试技术可以测量高速的微射流场。
The pulse in-line holography has been applized to construct the holography system and the high accuracy synchronization system.The hologram of microjet produced by explosive was gotten in the experiment. When the hologram was reconsructed, the distribution and the size of particle were analyzed. The statistical result of particles shows that the maximum size is 300μm and the minimum size is 30μm. This measurcment system was proved that the pulsed in line holography can measure the high velocity microjet.
