Non-invasive determination of constituent concentration using non-continuous radiation.

摘要

In an apparatus for non-invasive determination of the concentration of at least one analyte in a mammal, a portion of the body (31) of the mammal is irradiated by a radiation source (13) emitting two or more wavelength bands of near infra-red radiation. The radiation reflected from the portion of the body (31) is sensed by a spectrum analyser (21) and a value for the concentration of the analyte is derived by means of a date processor (23). <IMAGE>
