    摘要: Some embodiments of the present invention disclose systems and methods for a multiplexed multispectral imaging, object discrimination, background discrimination, and/or object identification. In some embodiments, a multispectral sensor is provided that includes at least two illumination sources and an imager with a color filter array. The two illumination sources can illuminate a platen with light having distinct illumination angles as well as distinct characteristics, such as distinct wavelengths or wavelength bands and/or distinct polarization conditions. The color filter array, which may be integral with the imager or separate therefrom, can filter light based on the specific distinctions between the two illumination sources. A single image of an object at the platen can be acquired. Individual pixels of the image will then be highly associated with one or the other illumination source. Because of the filtering by the color filter array, this image will include information about the illumination angle.

    摘要: Embodiments disclose a two imager biometric sensor. In some embodiments, the two imagers can include a direct imager and a TIR imager. In some embodiments, multispectral light sources can be used to illuminate target tissue imaged by two imagers. In some embodiments, composite images can be created from images detected using both imagers.
