| 摘 要： | 提出可直接检测干涉图的相对光强，解决基于干涉条纹的处理有效检测信息利用率不高的问题，得到全场相移的连续分布，从而重建被测火焰折射率场和温度场的方法．采用该方法对标准轴对称分布的火焰进行模拟计算，并与现有的采用逼近法处理干涉条纹获得的结果进行了比较，证明本文提出的方法精度较高，具有较好的应用价值．

| Abstract: | The direct measurement of the relative intensity in t he image of the holographic interferometry led to the continuous distribution of t he phase-shift. The temperature field and refractive index field in the flame c an be reconstructed. This method avoids extracting the available information wit h low efficiency from the interference fringes. Simulation on an axisymmetrical flame was carried out, and comparisons of the obtained results by the two method s were made. It was proved that the new method was much accurate and applicable. |
