The illumination source is disposed to provide light at multiple wavelengths to an object. The digital imaging system is disposed to receive light scattered from the object and has a digital array of light detectors and a color filter array. The color filter array has a multiple distributed filter elements, each of which is adapted to transmit light of one of a limited number of specified narrowband wavelength ranges. The color filter array is disposed to filter the light scattered from the object prior to encountering the digital array of light detectors. ## Claims ### Claim 1 A sensor comprising: an illumination source disposed to provide light to an object; and an imaging system disposed to receive light scattered from the object substantially without total internal reflectance (TIR) effects, wherein: the imaging system is configured to perform a biometric analysis of the object when the object comprises a skin site of an individual; and the imaging system is configured to read a barcode from the object when the object comprises the barcode. ### Claim 2 (depends on 1) The sensor recited in claim 1 wherein: the illumination source provides light to the object at a plurality of wavelengths; and the biometric analysis comprises a multispectral biometric analysis. ### Claim 3 (depends on 2) The sensor recited in claim 2 wherein the imagining system comprises: an array of light detectors; and a color filter array having a plurality of distributed filter elements, each filter element being adapted to transmit light of one of a limited number of specified narrowband wavelength ranges, the color filter array being disposed to filter the light scattered from the object prior to encountering the array of light detectors. ### Claim 4 (depends on 3) The sensor recited in claim 3 wherein the filter elements are distributed according to a Bayer pattern. ### Claim 5 (depends on 1) The sensor recited in claim 1 further comprising: a first polarizer disposed to polarize the light provided by the illumination source; and a second polarized disposed to polarize the light scattered from the object. ### Claim 6 (depends on 1) The sensor recited in claim 1 wherein the first and second polarizers are in a substantially crossed configuration. ### Claim 7 (depends on 1) The sensor recited in claim 1 wherein the imaging system is further configured to initiate a service in response to reading the barcode. ### Claim 8 (depends on 1) The sensor recited in claim 1 wherein the imaging system is further configured to generate an audit trail for the object in response to reading the barcode. ### Claim 9 (depends on 1) The sensor recited in claim 1 wherein the imaging system is configured to scan printed matter from the object when the object comprises the printed matter. ### Claim 10 (depends on 1) The sensor recited in claim 1 wherein: the printed matter comprises text; and the imaging system is further configured to convert the scanned printed matter to an interpretable form using optical-character-recognition techniques. ### Claim 11 (depends on 1) The sensor recited in claim 1 wherein: the illumination source is comprised by an illumination system; and the illumination system is configured to generate an image in response to receiving light scattered from the object. ### Claim 12 (depends on 1) The sensor recited in claim 1 wherein the imaging system comprises a focusing mechanism providing an adjustable focus to image the object. ### Claim 13 (depends on 1) A portable electronic device comprising the sensor recited in claim 1. ### Claim 14 (depends on 13) The portable electronic device recited in claim 13 wherein the portable electronic device comprises a cellular telephone. ### Claim 15 A method comprising: illuminating an object with light, the object comprising a barcode; receiving light scattered from the object substantially without total internal reflectance (TIR) effects; reading the barcode from the object with the received light scattered from the object; illuminating a skin site of an individual with light; receiving light scattered from the skin site; and performing a biometric analysis of the skin site from the received light scattered from the skin site. ### Claim 16 (depends on 15) The method recited in claim 15 wherein: illuminating the skin site of the individual comprises illuminating the skin site of the individual at a plurality of wavelengths; and performing the biometric analysis comprises performing a multispectral biometric analysis of the skin site. ### Claim 17 (depends on 15) The method recited in claim 15 further comprising initiating a service in response to reading the barcode. ### Claim 18 (depends on 15) The method recited in claim 15 wherein illuminating the skin of the individual and illuminating the object with light are perform in close temporal proximity. ### Claim 19 (depends on 15) The method recited in claim 15 further comprising generating an audit trail for the object in response to reading the barcode. ### Claim 20 (depends on 15) The method recited in claim 15 further comprising: illuminating a second object with light, the second object comprising printed matter; receiving light scattered from the second object; and generating an image of the printed matter from the second object with the received light scattered from the second object. ### Claim 21 (depends on 20) The method recited in claim 20 wherein the printed matter comprises text, the method further comprising converted the image of the printed matter to an interpretable form using optical-character-recognition techniques.
