Abstract
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.
Claims21
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.
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.
