Abstract

A two-color double exposure technique is proposed for recording two close states of an object on the same photographic film. The idea is to use a two-color laser for illumination, one color for each state of the object, and a single photographic plate. After being developed, the image of each state may be observed separately. The technique is demonstrated for the deferred moire deflectometry where two closely displaced fringe patterns have to be recorded and resolved.

摘要

提出了一种双色双曝光技术,用于在同一张照相底片上记录物体的两个相近状态。其思路是使用双色激光进行照明,每种颜色对应物体的一种状态,并使用一块照相底片。显影后,可以分别观察到每种状态的图像。该技术在延迟莫尔偏折术中得到了验证,在这种情况下需要记录和分辨两个紧密相邻的条纹图案。
