摘要： A method of making an optical waveguide. First ultraviolet light is radiated upon the surface of a transparent piece of photopolymerization material of a type whose refractive index is changed by the impact of ultraviolet light thereon, so that a refractive index profile in the depthwise direction of the piece of photopolymerization material is formed. Next ultraviolet light is radiated upon the surface of the transparent piece of photopolymerization material in a pattern of a lengthwise extending stripe whose intensity is least in its central portion and becomes greater towards its edge portions, so that a refractive index profile in the widthwise direction of the piece of photopolymerization material is formed. Finally an optical waveguide is structured from the thus irradiated piece of photopolymerization material. Optionally, these profiles may be parabolic profiles. Optionally, also, the structuring of the final optical waveguide may be done by laminating together two similar such pieces of photopolymerization material, thus treated, with their sides which were exposed to ultraviolet radiation in contact with one another.

摘要： An image processing device is disclosed which can reliably detect documents which may not be copied, which has a very small probability of false positives, and which can handle newly issued documents which may not be copied. In addition, an image processing scheme is disclosed which would accurately obtain the location of a pattern indicating a document to be detected; which would extract that pattern; which would determine correctly whether it is the right pattern; and which would make it difficult for anyone to tamper with the pattern. To achieve this, a specified pattern is imprinted before use on a document which may not be copied, and a previously specified number of positioning marks and dummy marks which identify the location of the pattern may also be imprinted. The device is able to detect a wide variety of documents and perform the required processing at high speed.
