Abstract

"A theoretical and experimental investigation of the causes of the reduction of the contrast in the shadow of a grating has been made. The variation of the shadow contrast is shown to be different for the two causes--diffraction and divergence. The conditions which determine the dominant effect are presented. Also, the contrast pattern due to diffraction is shown to have a squared scaling law while the divergence pattern is shown to scale linearly. This understanding of the shadow contrast increases the versatility and usefulness of the shadow moire technique, an optical method for determining the topography of surfaces"--Abstract, page ii.
