Method and apparatus for performing near-infrared (NIR) quantitative analysis includes the steps of providing NIR radiation at a plurality of different wavelengths for illumination of an object to be analyzed and varying the , amount of time that radiation at each wavelength illuminates the subject according to the output level of radiation at each wavelength so as to provide substantially similar detection data resolution for each of the plurality of wavelengths. The method is particularly applicable to non-invasive quantitative measurement of blood analytes such as blood glucose levels using , low cost IREDs operating outside their one-half power bandwidths.

Why it's free to use
- Filed February 13, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 13, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 13, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
