A new method of moire topography is described. This encompasses two processes: recording of the deformed grating projected onto a 3-D object, and posterior development of contour moire from the record. The development of contour moire is realized by projecting a linear grating onto a photographic print of the record of the deformed grating, using a photographic enlarger. By this new method, a technique for describing a 3-D object by means of the slope of facets composing the object is made possible.
本文描述了一种新的云纹形貌测量方法。该方法包括两个过程：记录投射到三维物体上的变形光栅，以及随后从记录中生成等高线云纹。等高线云纹的生成是通过使用照相放大机将线性光栅投射到变形光栅记录的照片上实现的。通过这种新方法，可以实现一种利用构成物体的小平面斜率来描述三维物体的技术。
