Abstract
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 wavelength ranges within the continuous spectrum; and using the determined intensity to calculate the concentration of the constituent. A radiation source including a radiating bulb and a chopper for periodically interrupting radiation emitted from the bulb may be provided.
