    摘要: The present invention discloses a method and apparatus in relation to non-invasive measurement of human blood analytes such as glucose using Raman Spectroscopy. The method is intended to correct for errors associated with varying skin conditions. An approach is described for generating a skin/tissue function that accounts for light energy dissipation due to skin and tissue interferences such as color, thickness, sites, oily, turbid, and surface roughness, etc. The measured skin/tissue function is utilized to correct Raman spectra, thus removing uncertainty and ambiguity coming from skin conditions. The method comprises measuring incident broadband spectrum and diffuse reflectance spectrum, and from them calculating the skin-tissue function.

    摘要: The present invention discloses a method and apparatus and method for achieving non-invasive measurement of analytes from human and animal blood through the skin using Raman lightwave technology. The apparatus includes a confocal signal collection system that effectively reduces the interferences from out-of-focus signals. The apparatus further includes a tissue permeation unit, which controls the amount of blood in the laser tissue interaction region. The change of aggregate spectra with time is used to construct a new series of differenced spectra, from which the spectral effects from surrounding static substances are calibrated out dynamically using the data processing method described.
