Abstract:
Embodiments are described of a color filter array including a plurality of tiled minimal repeating units. Each minimal repeating unit includes an invisible-wavelength filter layer including a plurality of filters and a visible-wavelength filter layer positioned on the invisible-wavelength filter layer and having a plurality of filters such that each filter from the visible-wavelength layer is optically coupled to a corresponding filter in the invisible-wavelength layer.
