摘要
This paper discusses moire and holographic methods with enhanced measurement sensitivity for visualizing macroscopic surface defects of an object with a periodic structure, using the slit mask of a television picture tube as an example. Moire and interference patterns are presented with various measurement sensitivities, visualizing the surface defects of the picture-tube mask.
