Instrument and method for non-invasive monitoring of human tissue analyte by measuring the body's infrared radiation

摘要

The invention relates to a method for determining a human body tissue analyte concentration by a non-invasive measurement, comprising the steps of a. detecting emission spectral lines characteristic to the body tissue analyte in an infrared spectral region emitted naturally by a human body as heat radiation, wherein said emission spectral lines have a wavelength dependence on tissue constituents; b. measuring a spectral intensity of the emission spectral lines at a predetermined emission wavelength; c. analyzing the emission spectral lines in said infrared spectral region; d. correlating said spectral intensity of the emission spectral lines with a body analyte concentration.
