Reducing the optical effects of domes
This application discloses an apparatus for minimizing the optical effects of transmissive domes, and for using the dome surfaces to correct for other optical aberrations and distortions. Herein, the inner surface of the dome is designed to correct for unwanted optical effects of the outer surface of the dome and may also be used to correct for other anticipated effects in the overall optical system.
1. An apparatus for the correction of dome aberrations comprising:
a dome comprising a curved shell comprising an inside surface and an outside surface;
wherein the inside and outside surfaces of the dome comprise two separate shapes that combine to form a corrector that improves the quality of the image formed or the information collected by an imaging-system underneath the dome;
wherein the dome comprises a material capable of transmitting radiation; and
wherein the dome comprises an ultraviolet light blocking material, an infrared light blocking material, a visible light blocking material, or mixtures thereof.
2. The apparatus of claim 1 wherein the inside surface of the dome comprises a shape that counteracts aberrations or distortions induced by the outside surface of the dome.
3. The apparatus of claim 1 wherein the dome surfaces comprise conic sections.
4. The apparatus of claim 1 wherein the dome surfaces comprise conic sections that are concentric.
5. The apparatus of claim 1 wherein at least one dome surface comprises a three-dimensional function that is not a conic section.
6. The apparatus of claim 1 wherein at least one of the dome surfaces comprises a localized function applied as a variation to an overall shape function.
7. The apparatus of claim 1 wherein the outside surface of the dome is designed for aerodynamic properties, imaging, radiation-collection properties, or a mixture thereof.
8. The apparatus of claim 1 wherein the dome comprises a material comprising enhanced reflection, transmission, absorption, or mixtures thereof, across some part of the electromagnetic spectrum.
9. The apparatus of claim 1 wherein the dome comprises a spheroidal shape, an ellipsoidal shape, or an ogive shape.
10. The apparatus of claim 1 wherein the dome comprises an uneven thickness.
11. The apparatus of claim 1 wherein the dome comprises a variable thickness.
12. The apparatus of claim 1 wherein the dome comprises an inside surface constructed as a combination of one or more surface patterns.
13. The apparatus of claim 1 wherein the dome comprises one piece or multiple pieces.
14. The apparatus of claim 1 wherein the dome comprises one layer, multiple layers, or a mixture thereof in different locations on the dome.
15. The apparatus of claim 1 wherein the dome comprises one pane or multiple panes.
16. A method for correcting dome aberrations comprising:
(a) designing a dome comprising a curved shell comprising an inside surface and an outside surface;
wherein the inside and outside surfaces of the dome comprise two separate shapes that combine to form a corrector that improves the quality of the image formed or the information collected by an imaging system underneath the dome;
wherein the dome comprises a material capable of transmitting radiation; and
wherein the dome comprises an ultraviolet light blocking material, an infrared light blocking material, a visible light blocking material, or mixtures thereof; and
(b) manufacturing the dome by adjusting a curvature of the inside surface of the dome to correct for any aberrations induced by a curvature of the outer surface.
