Abstract
A method is developed whereby the accuracy of Ligtenberg's reflective moiré method for plates can be improved. The method uses the linear and rotational mismatches to increase the fringe densities along directions parallel and perpendicular to the grating lines. As a result greater precision can be obtained in the plotting of curves of partial slopes which are used for determination of curvatures and twists of the flexed plate.Keywords
