ABSTRACT:
An optical imaging apparatus according to the present invention comprises a flat multilens array having a number of lenses arranged in a row and a flat multiprism array having a number of prisms also arranged in a row and located behind the multilens array such that its individual prisms are aligned with the individual lenses. Two prism surfaces (flat reflecting surfaces) are positioned at one side and a single lens surface (curved surface) at the other and multiple combinations of such surfaces are lined up in an array. Each lens or each prism has on its front end a light intercepting screen plate having a substantially oblong opening which is shorter in the direction of the array and longer in a direction perpendicular thereto, or the aperture of each prism and/or each lens itself is shaped so. For the correction of abberations, one or more additional lenses of different curvatures are stacked on the front end of each lens to constitute a composite lens system. The multiprism array is replacable by a multiroof prism array.
