摘　　要：多方向全息干涉法是获得三维流场重构数据的较好方法,采用离轴式像面全息干涉技术从正交两方向对同一流场进行显示,得到了模型流场清晰的序列全息干涉图,可用于三维重构数据提取的需要。同时,采用CFI仿真结果进行对比验证。通过对该研究的总结和分析,为今后多向(≥6方向)全息干涉技术测量湍流流场奠定了基础,同时也提出了下一步工作的相关想法。The multi-direction holographic interferometry is one of the instruments for measuring three-dimensional flow fields.In this paper,a technique that visualizes flow fields with off-axis image plane holographic interferometry in two orthogonal directions simultaneously is developed.Sequences of interferograms of flow fields are obtained by this technique,which could be used to reconstruct three-dimensional flow fields.The measured results are compared to CFI simulation results with qualitative agreement.This research is a basis of a three-dimensional visualization of turbulent flows by using multi-direction（≥6） holographic interferometry.Future research direction and thoughts are indicated.
