ABSTRACT:
An optical system simulates the optical effect of traveling over a large distance on light traveling from a first reference surface to a second reference surface. The first and second reference surfaces are relatively closely spaced. A first afocal magnifying lens system receives light from the first reference surface and provides a magnification ratio of M.sub.1. A second afocal magnifying lens system, spaced from the first afocal magnifying lens system by a predetermined distance D, receives light from the from the first afocal magnifying lens system and transmits it to the second reference surface with a magnification ratio of M.sub.2. The length of the distance which is simulated is related to the magnification ratio M.sub.1 of the first afocal magnifying lens system and to the predetermined distance D. The scale of the output image is related to magnification ratio M.sub.2.
