| 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. |
