摘要
We previously proposed the scanning moire method in which the scanning lines of a TV camera or the sampling points of an image processor interfere with the specimen grating lines to create a moire pattern. This method produces clear moire patterns eliminating original grating lines. The sampling pitch is easily changed by selecting a thinning-out index. However, an image with a large thinning-out index creates a jaggy pattern. In this paper, we propose a new scanning moire method to produce smooth fringe patterns without jaggy fringes from phase-shifted grating patterns.
