Paper Abstract

A simple and straightforward way to make projection Moire topograms is described. A grating pattern is projected on the object, which is imaged by an interline transfer (ILT) charge coupled device (CCD) television camera. High contrast Moire fringes that can be equal to topographical contours are then obtained. Experiments showing examples of this technique are presented and discussed.
