摘要
This paper proposes the simple technique for evaluating a straight edge using the interference phenomena in the shadow region of various sample edges. Evaluation is easier and more effective in the shadow region than in the bright region because of the higher sensitivity of an edge to a shadow's diffraction pattern.
