Fixed Focal Length Lens Array

This figure shows a lens array, where each lens has a fixed focal length, in a highly curved state. Notice the large black areas (gaps) between the fields of view (yellow regions) of adjacent lenses. These gaps lead to aliasing in the captured image. We could attempt to eliminate the gaps by increasing the field of view of each lens, but this would lead to blurring in the captured image when the lens array is flat.
