Abstract
An apparatus and method for acquiring and analyzing a spectroscopic sample for a substance from a sampling region of the tissue of a person at an interstitial region between the fingers of the person, by way of a probe and a spectroscopic detector for radiating the interstitial region with electromagnetic radiation and analyzing a diffuse-reflectance signal obtained from the tissue at the sampling region. The apparatus preferably also incorporates a biometric sensor to perform a verification of the person.
Claims34
An apparatus for acquiring and analyzing a spectroscopic sample for a substance from a sampling region of the tissue of a person, the apparatus comprising:
- a source of electromagnetic radiation;
- a probe for delivering the electromagnetic radiation to the tissue at the sampling region and obtaining a diffuse-reflectance signal from the tissue at the sampling region;
- and
- a spectroscopic detector for analyzing the diffuse-reflectance signal for presence of the substance.
A method of non-invasive spectroscopic detection of a substance from the tissue of a person, the method comprising:
- impinging electromagnetic radiation on a sampling region of the tissue of the person;
- obtaining a diffuse reflectance signal from the tissue at the sampling region;
- and
- spectroscopically analyzing the diffuse-reflectance signal for presence of the substance.
