The moire 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. Moire interferometry is dealt with at some greater length, and questions that are frequently raised concerning moire 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.

General equations are developed which relate the characteristics of moiré fringes to the geometry of two superposed, dissimilar grid systems. Equations are derived geometrically, assuming the rectilinear propagation of light, and the analysis is restricted to a consideration of linear, periodic, mutually inclined systems. Criteria are established for the production of first and second order fringe systems, and some particular cases of grid geometry are examined in detail. The concepts of mixed grids and hybrid grid combinations are introduced, and the principles and possible applications of fringe sharpening, fringe multiplication and dual sensitivity systems are discussed.
