Abstract
A device including an array of pixels and a filter wheel may capture a plurality of images by exposing the array of pixels. The device may spin, while capturing the plurality of images, the filter wheel, and the filter wheel may include filter segments. In some implementations, a portion of the filter wheel in front of the array of pixels includes two or more filter segments.
Claims20
A device, comprising:
- an imager;
- and
- a filter wheel that includes filter segments that form a hyperspectral filter array and are positioned in the filter wheel in a repeating sequence, wherein at least a portion of the filter wheel is positioned in front of the imager, and
- wherein the device is configured to spin the filter wheel in a manner that one or more filter segments, of the filter segments, pass over the imager.

A device, comprising:
- an imager;
- and
- a filter wheel including a plurality of filter segments positioned in the filter wheel,
- wherein at least a portion of the filter wheel is positioned in front of the imager,
- wherein the plurality of filter segments includes a filter segment,
- wherein the filter segment includes a first subsegment and a second subsegment positioned along a length of the filter segment, and
