Claim Text:
1. An optical device for mapping a curved image field, the optical device comprising: a focal plane array having a plurality of light processing elements; and a focal plane adapter mounted in front of the focal plane array configured to transmit the curved image field to the light processing elements of the focal plane array, wherein the focal plane adapter comprises a plurality of waveguides, wherein first ends of the waveguides facing the curved image field are arranged on a curved surface, the curved surface being adapted to a profile of an optical field curvature of the curved image field so that the plurality of waveguides divide the curved image field along a curved focal plane of the image field into a plurality of image segments, wherein second ends of the waveguides are allocated to the light processing elements to map the plurality of image segments onto the allocated light processing elements, and wherein the focal plane adapter is a hollow waveguide array, wherein the curved surface is an elliptical paraboloid.
