ABSTRACT:
An optical imaging device divides a long thin object, such as a line of print, into several sections and arranges the sections into an overlapping image, of area form as compared to the original linear form of the object. A plurality of lenses are used, each lens associated with a particular section of the object. Each lens is tilted relative to the other lenses so that the plane of the lens is perpendicular to the line connecting the center of the related image section and object section, and also displaced in a direction normal to the extent of the line of lenses so that the center of each lens is on the line connecting the center of the related image section and object section. The lenses can extend in a curve to reduce magnification variations from lens to lens, and conveniently the lenses are rectangular and molded as a single unit.
