Abstract
Created by an optical interference of two closely spaced arrays of lines or grids, the moire effect is a phenomenon offering a convenient means of detecting large field inplane displacements for strain analysis. This pioneering study carried out by the Bureau of Mines develops an experimental technique for using the moire method in making remote full field strain distribution measurements for rock fragmentation study. The paper briefly explains the basic principles of the moire method and its significance to measure strain distribution during rock testing.
