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.
