Abstract

The shadow moire method is used in conjunction with a Liquid Crystal Display (LCD) projection panel onto which is written a computer generated grating to display contours of the topography of objects. The ability of rapidly changing the parameters of the grating like the pitch and width of lines through the software makes this a versatile tool for shadow moire applications. Demonstration of the technique including means for rapid image enhancement are described in this paper.
