Multimodal biometric device
A multimodal biometric device is disclosed. An apparatus may include a non-contact imaging system. The non-contact imaging system may include imaging optics, optical illumination optically coupled to the imaging optics, and a configurable body part support to support different body parts at corresponding focal lengths to capture different portions of the different body parts. An apparatus may also include a housing coupled to the imaging optics, the optical illumination, and the configurable body part support.
1. An apparatus comprising:
a non-contact imaging system, the non-contact imaging system comprising;
imaging optics;
optical illumination optically coupled to the imaging optics; and
a rotary top comprising selectable apertures to support different body parts, each aperture characterized by one or more of a different size and a different shape relative to the other selectable apertures; and
a housing comprising an opening and coupled to the imaging optics, the optical illumination, and the rotary top;
wherein the rotary top is configured to rotate to align a selected aperture of the selectable apertures with the opening of the housing.
2. The apparatus of claim 1 , wherein one of the different body parts comprises one or more fingers, a palm pad, a palm, and a ball of a foot.
3. The apparatus of claim 1 , wherein the housing blocks ambient external light from the non-contact imaging system during imaging of the body part.
4. The apparatus of claim 1 , wherein the non-contact imaging system captures images at a resolution of at least 1000 pixels-per-inch.
5. The apparatus of claim 1 , wherein the non-contact imaging system comprises one or more cameras.
6. The apparatus of claim 1 , wherein the non-contact imaging system comprises one or more of a CMOS and CCD imager, and wherein the non-contact imaging system is monochromatic or color detecting.
7. The apparatus of claim 1 , wherein the imaging optics comprises a fixed focus and a fixed focal length or an adjustable focus and an adjustable focal length.
8. The apparatus of claim 1 , wherein the optical illumination comprises one or more colors of LEDs over a range of wavelengths from UV through NIR.
9. The apparatus of claim 1 , wherein the apparatus further comprises:
imagers; and
illumination, wherein the imagers and the illumination collect additional types of biometric images.
10. The apparatus of claim 1 , wherein a portion of interest accommodated by a selectable aperture exposes the portion of interest to the imaging optics and the optical illumination to provide non-contact imaging of the portion of interest.
11. The apparatus of claim 1 , wherein the apparatus is further configured to measure a health parameter of a subject using the imaging optics and the optical illumination.
12. The apparatus of claim 1 , wherein the different body parts comprise fingers of different sizes.
