Fringe shifting in various moire methods
Abstract
Fringe shifting can be used for reading fractional fringe order and the determination of fringe sign. Its application so far has been limited to the in-plane moire method. In this paper the concept of fringe shifting is extended to the shadow moire method, the reflection moire method, and the image moire method. Practical procedures necessary for the shifting are also presented.
