Abstract
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.
