An automated technique is described that uses holographic interferometry to determine the translation of a diffusely reflecting rigid body. The photographs of the reconstructed virtual image of a double-exposed hologram were digitized. The CDC 6600 computer was used to process the reconstructed virtual image data by recording the number of fringes that moved over specified image points as the viewing direction of the hologram was varied. Contours were made by connecting all image points over which an equal number of fringes passed. A surface resolution (distribution of image points interrogated) of 0.0368 cm was used. By using this technique a 6.35-microm linear displacement of a 3.68-cm diam aluminum object was verified with an error </=4.3% over the entire object. It appears this technique can be extended to three-dimensional objects.
描述了一种自动技术，该技术使用全息干涉测量法来确定漫反射刚体的平移。对双曝光全息图重建的虚像照片进行数字化处理。使用CDC 6600计算机处理重建的虚像数据，通过记录当全息图的观察方向改变时在指定图像点上移动的条纹数量。通过连接有相等数量条纹通过的所有图像点来绘制等高线。使用的表面分辨率（被询问的图像点分布）为0.0368厘米。通过使用该技术，验证了直径为3.68厘米的铝制物体有6.35微米的线性位移，在整个物体上误差≤4.3%。看来该技术可以扩展到三维物体。
