Moiré Strain Analysis: An Introduction, Review and Critique, Including Related Techniques and Future Potential.

The moiré fringe method is described and reviewed with particular reference to its application in strain analysis. The theory is briefly dealt with, followed by a discussion of the common methods used to analyse the information that the fringes contain and then certain non-obvious limitations are discussed. The generic grid-preparation techniques and optical arrangements are described. Moiré interferometry is dealt with at some greater length, and questions that are frequently raised concerning moiré in comparison to somewhat similar methods are addressed. Specific difficulties are indicated and the work concludes with a consideration of some recent work that may influence future developments of the method. Of necessity, there is much reliance on reference to quoted works. [ABSTRACT FROM AUTHOR]
