Abstract

For the moire visualization of macroscopic defects in composite periodic structures by comparing a structure under study with the reference, it is proposed that rerecorded moire patterns from each of the substructures be used as reference ones. The use of the rerecorded moire patterns obtained by filtering complex conjugate orders of diffraction improves the sensitivity of the method.
