Patent Images
1. A lens comprising:
- multiple lens elements configured to focus an image from an asymmetric imaging component, the multiple lens elements including;
at least one optical lens element configured to redirect the image so that the image passes through the lens; and
at least one asymmetric lens element configured to at least partially correct aberration in the image caused by the asymmetric imaging component, the at least one asymmetric lens element configured to at least partially remove the aberration from the image without reducing a size of an aperture of the lens and without tilting the lens relative to an axis that runs substantially through center portions of said asymmetric lens element.

Abstract
An asymmetric aberration correcting lens is described. In one or more implementations, a lens includes multiple lens elements that are configured to focus an image from an imaging component. The multiple lens elements include an optical lens element that is configured to redirect the image so that the image passes through the lens. Further, the multiple lens elements include an asymmetric element configured to correct asymmetric aberration caused by the imaging component.

8. A device comprising:
-
an asymmetric imaging component configured to collect an image but introduces aberration into an image that passes through the asymmetric imaging component, the asymmetric imaging component having a wedge that is configured to funnel collected images to an exit portion of the asymmetric imaging component; an imaging sensor configured to detect the image; and a lens comprising at least one asymmetric lens element configured to at least partially remove the aberration from the image, the lens disposed about an axis that runs between the asymmetric imaging component and the imaging sensor and the at least one asymmetric lens element is configured to at least partially remove the aberration from the image without tilting the lens relative to the axis. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. A method comprising:
-
collecting images through an imaging component that introduces asymmetric aberration into the images, the asymmetric imaging component having a wedge that is configured to funnel collected images to an exit portion of the asymmetric imaging component; removing the asymmetric aberration from the images using a lens that includes an asymmetric lens element, the lens disposed about an axis that runs between the asymmetric lens element and a sensor and the asymmetric lens element configured to at least partially remove the aberration without tilting the sensor relative to the axis; and detecting the images with the sensor, the detected images excluding the asymmetric aberration from the imaging component. - View Dependent Claims (18, 19, 20)
