发明名称 Imaging optical system using index distribution type optical elements
摘要 An imaging optical system using index distribution type optical elements comprises an imaging optical system for forming the image of an object on a light receiving surface, is formed by a plurality of optical elements of erect one-to-one magnification having a radial index distribution arranged in a row and satisfies the following relations: <IMAGE> where x is 0 or greater integer, D is the effective diameter of each optical element, Xo is the field radius of each optical element, and P is the arrangement interval of the optical elements.
