| 摘 要： | 本文将普通纹影仪改造成激光差分干涉仪，并用于火焰等密度场的显示与测量。编制了条纹预处理和细化软件系统，并对干涉条纹进行了处理和细化计算。另外，针对细化后的条纹，编制了密度场的计算软件，并对蜡烛火焰和超声速轴对称绕流流场进行了计算，得到了密度场定量的结果。

| Abstract: | A schlieren was changed into a interferometer and which has been used in measurement and visualization of density field. The programs of interferogram strips processing and the programs of density field calculation are worked out, and which have been used in density field calculation of candle flame and supersonic axisymmitric flow. |
