ABSTRACT:
A fiber optic elment is used to correct or reverse a field curvature distortion in an optical system having two imaging elements. The fiber optic element has fibers arranged in parallel with their first ends along a curvature corresponding to the expected field curvature of the image from the first imaging element, and second ends along another curvature for producing a correct output image. In the two-element optical system, the fiber optic array has its second ends arranged to provide an input object to the second imaging element with a reversed field curvature such that a correct output image is obtained from the second imaging element.
