Multispectral barcode imaging

摘要

A multispectral sensor is provided with an illumination source and a digital imaging system. 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.

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; andthe imaging system is configured to read a barcode from the object when the object comprises the barcode.
