ABSTRACT:
In an imaging optical system, the angular aperture of distributed index optical elements which are optical elements forming the imaging optical system is 9.degree. or greater and the degree of superposition M of images on a light-receiving surface is M=2.75+0.5x. The degree of superposition M of images is represented by M=X.sub.0 /D, where D is the effective diameter of the optical elements and X.sub.0 is the field radius thereof. Also, x is 0 or a greater integer.
