Imaging optics and optical device for mapping a curved image field
First Claim
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, andwherein the focal plane adapter is a hollow waveguide array, wherein the curved surface is an elliptical paraboloid.

Abstract
The present invention relates to optical devices for imaging and spectroscopic applications where optical field curvature is a predominant characteristic. In particular, the invention relates to imaging optics and an optical device for mapping a curved image field. The optical device for mapping a curved image field comprises a focal plane array 20 having a plurality of light processing elements 21 and a focal plane adapter 110 mounted in front of the focal plane array 20 configured to transmit the curved image field to the light processing elements 21 of the focal plane array 20. The focal plane adapter 110 comprises a plurality of waveguides 111 wherein first ends of the waveguides 111 facing the incident curved image field are arranged on a curved surface 12, the curved surface 12 being adapted to a profile of an optical field curvature of the curved image field so that the plurality of waveguides 111 divide the curved image field along a curved focal plane of the image field into a plurality of image segments. The second ends of the waveguides 111 are allocated to the light processing elements 21 to map the plurality of image segments onto the allocated light processing elements 21.
