计算干涉技术通过试验图像和计算图像相比较，可以验证CFD的有效性，是研究复杂流场的有力工具。作者根据M-Z干涉仪的光学成像原理，用计算机仿真实现了将数值计算获得的二维、轴对称和三维的复杂流体的密度场转换为“无限条纹”和“有限条纹”的干涉图像，尤其是在处理三维流场时，采用流场重构的方法，达到了很好的效果。%In present paper,a technology (including a computed optical device and digital image process) of computational interferometry for complicated 3-D steady and unsteady flow is described.A good agreement between computational holographic interferogram for 3-D shockwave flow and experimental ones shows that this technology is a powerful tool for CFD and experimental research in complicated 3-D flows.
