Abstract
The present invention is related to optical non-invasive methods and instruments to detect the level of analyte concentrations in the tissue of a subject. The spectra of mid-infrared radiation emitted from a subject'"'"'s body are altered corresponding to the concentration of various compounds within the radiating tissue. In one aspect of the invention, an instrument measures the level of mid-infrared radiation from the subject'"'"'s body surface, such as the eye, and determines a specific analyte'"'"'s concentration based on said analyte'"'"'s distinctive mid-infrared radiation signature.
