Image sensor with a plurality of light channels
First Claim
1. An eye-mountable device comprising:
- a polymeric material that can be removably mounted over an eye;
a substrate at least partially embedded in the polymeric material; and
an image sensor disposed on the substrate, wherein the image sensor includes;
a plurality of photo-sensitive elements in one-to-one correspondence with a plurality of light channels, wherein the plurality of light channels have a plurality of different orientations with respect to a central optical axis such that each photo-sensitive element receives incident light from a respective direction defined by a corresponding one of the plurality of light channels, and wherein each light channel has a first end through which incident light enters the light channel and a second end that is closer to the central optical axis through which light passes from the light channel to a corresponding one of the photo-sensitive elements, wherein each of the light channels is formed by a plurality of interconnected apertures patterned in a plurality of opaque layers stacked over the photo-sensitive elements.

Abstract
An eye-mountable device includes an image sensor situated in a polymeric material configured to be mounted to a surface of an eye. The image sensor can be disposed on a substrate at least partially embedded in the polymeric material. The image sensor can include a photo-sensitive area occupied by a plurality of photo-sensitive elements. The photo-sensitive area is illuminated by light entering a plurality of light channels. Each of the light channels has a respective orientation such that light passes through a given light channel from a respective direction. A given portion of the photo-sensitive elements therefore receives light from a respective direction corresponding to the one of the light channels that illuminates it. The direction-specific measurements of received light obtained by the multiple photo-sensitive elements can thereby be used to form an image.
