Abstract
Interference fringes are produced by a simple method, i.e., irradiating a convex face with coherent light. This method can only be used if the face has a mirror surface and the profile of the convex face is expressed by a mathematical function with a point of inflection. This convex face is generally shaped where a thin plate is deformed by pressure. Interference fringes are made wherever reflected light propagates and is clear even in high fringe order ranges.
