NON-INVASIVE MEASUREMENT OF ANALYTE CONCENTRATION IN BLOOD

摘要

The method for non-invasive detection of the concentration of a constituent in blood of a living animal includes the steps of irradiating a body part of the animal with intensity modulated radiation over a continuous spectrum, determining the intensity of radiation emitted from the body part at a wavelength ranges within the continuous spectrum; and using the determined intensity to calculate the concentration of the constituent. A radiation source (15) including a radiating bulb (18) and a chopper (20) for periodically interrupting radiation emitted from the bulb, may be provided.
