Abstract
A camera system includes a mosaic optical color filter array, which includes a plurality of repeating unit cells that enforce spectral consistency and spatial uniformity. Each repeating unit cell of the plurality of repeating unit cells satisfies a minimum focal-plane array perimeter criterion and a minimum perimeter to area ratio criterion. The spatial arrangement of bands within the repeating unit cell minimizes inter-band correlation between nearest neighbors. The camera system further includes as short-wave infrared detector optically coupled to the mosaic optical color filter array. Optionally, the mosaic optical color filter array includes at least five spectral bands. The plurality of repeating unit cells includes the at least five spectral bands.
