A master camera. scanning-moire method is a moire method in which the grating is replaced by the scanning lines of a television In the present paper, the principle of moire pattern appearance. the effects of thinning out of scanning lines and the relation between moire fringes and strain are studied by the sampling theorem. If deformed model gratings are sampled by a television camera and they are thinned out properly by using an image processing system, the strain distribution in a wide strain range can be analyzed from one picture.
