Abstract

A specimen grating design with two linear rulings with axes 60° apart is proposed for strain analysis using moire and moire interferometry techniques. The grating facilitates derivation of three displacement patterns using one analyzer grating or a single pair of illuminating beams. Advantages relating to the grating technology and experimental setup) simplification are discussed. The results of experiments are presented.
