本文论述了双曝光全息干涉法在激波流场研究中的应用．对于形状不规则模型在超音速风洞中产生的激波流场，由于对这种流场进行数值计算几乎不可能，从实验上对其进行定量测量就显得尤为重要．本文很好地解决了某种不规则模型超音速激波流场的定量测量问题，获得了激波流场的有限条纹全息干涉图，并利用图象处理技术对干涉图进行了细化处理，再用人机交互的方式采集数据计算出条纹的位移量，最后用拉普拉斯变换法计算出流场的密度分布值．
This paper discusses the application of double exposure holographic interferometry in the study of shock wave field. For the shock wave field generated by the irregular-shaped model in a supersonic wind tunnel, it is very important to quantitatively measure the flow field numerically because it is almost impossible to do numerical calculation. This paper solves the problem of the quantitative measurement of supersonic shock field in an irregular model, and obtains the finite fringe hologram interferogram of the shock field. The interferogram is refined by the image processing technology, And then use human-computer interaction to collect data to calculate the stripe displacement, and finally use Laplace transform method to calculate the density distribution of the flow field value.
