Lens system for redirecting light rays within a field of view toward a focal plane

摘要

A system for displaying an anamorphic image on a viewing surface comprises a screen having a viewing surface and an image source configured to display the anamorphic image on the viewing surface such that an image viewed on the viewing surface appears undistorted from a viewing point. In addition, the system may also include a reflective lens having a convex exterior surface and a refractive lens having a plurality of surfaces to redirect light toward an image capture device. Further, the system may include an image conversion module for converting a non-anamorphic image into the anamorphic image suitable for displaying on the viewing surface and a selected portion of the anamorphic image into at least one non-anamorphic image.

1. A lens system for redirecting light rays within a field of view toward a focal plane, the lens system comprising:
a first lens having a semispherical exterior surface opposite a non-spherical interior surface; and a second lens adjacent the first lens, the second lens having a non-spherical interior surface opposite a non-spherical exterior surface, wherein the semispherical exterior surface defines a center point, the semispherical exterior surface does not refract the light rays heading toward the center point, and the interior surface of the first lens, the interior surface of the second lens, and the exterior surface of the second lens are configured to in combination refract the light rays originally heading toward the center point to a focal point between the focal plane and the center point.
