A holographic interferometric technique is proposed whereby the interference fringes map one of the in-plane displacement components. The technique operates in real time by illuminating the undeformed object frontally and using two holograms to record two symmetrically scattered waves. On observation, the conjugates of the waves impinge on the object and reconstruct its real image. If the object is deformed, interference fringes can be seen on its surface. Some results obtained by a simplified setup are presented.
提出了一种全息干涉测量技术，通过该技术干涉条纹可映射平面内位移分量之一。该技术通过正面照射未变形的物体并使用两个全息图记录两个对称散射波来实时运行。在观察时，波的共轭波撞击物体并重建其真实图像。如果物体发生变形，在其表面可以看到干涉条纹。给出了通过简化设置获得的一些结果。
