Abstract
The analysis of Livnat and Post (Experimental Mechanics, 25(4) (1985) 360-6) is used to show that the fringe patterns observed using grating s at +/-450 to the desired displacement components (as discussed by Cz arnek and Post (Experimental Mechanics, 24(1) (1984) 68-74) correspond to the fringes observed using geometric moire gratings aligned with t he measurement axes. Such gratings may be interrogated with a three-la ser-beam interferometer as described by McDonach et al. (Optics and La sers in Engineering, 1 (1980) 85-105).
