摘要：
A light beam is periodically chopped and then converted to a plane of light by a cylindrical lens. As the plane of light is chopped, it is caused to scan an object in the direction normal to the plane of the light to form a grating pattern on the object. The image of the grating formed on the object is superposed with a standard grating to obtain a moire pattern which represents the moire contour lines of the object.
