ABSTRACT:
A terrestrial imaging device includes an objective lens which accepts light within an intrinsic angular field of view onto a focal plane and two pairs of plane mirrors. The first pair of plane mirrors reflects a first light incoming ray sequentially to produce first and second reflected light rays within a roughly horizontal plane, the second reflected ray being focused by the objective lens on the focal plane. The second pair of plane mirrors reflects a second incoming ray sequentially to produce third and fourth reflected light rays within a roughly vertical plane, the fourth reflected light ray being focused by the objective lens on the focal plane.
