摘要： 纳秒级脉冲红宝石激光器作光源、一次成像的Polaroid相机接收图象的M－Z干涉系统用于超音速混合及燃烧流场的测量获得了清晰的干涉照片。利用计算机图像处理技术及自行开发的干涉图处理软件对获得的干涉图进行了处理，得到定量的燃烧流场密度分布。

Abstract: The clear interferograms of supersonic mixing and combustion flow field are obtainedby using Mach-Zehnder interferometer with a pulsed ruby laser, which is employed in pulsewidthrange of nanosecond as light source,and a Polaroid camera recording pictures. The interferograms areprocessed by a self developed computer interferogram processing system. The quantitative densityprofiles of flow field are shown.
Key words: Supersonic combustion;Flow distribution;Laser measurement;Interferogram;Computer techniqne
