METHOD OF AND APPARATUS FOR MULTIPLE-SPECTRUM NON-INVASIVE NEAR IR SPECTROSCOPIC ANALYSIS |
摘要 |
An apparatus is provided for determining the concentration of an analyte present in a sample using multi-spectral analysis in the near-infrared (NIR) range. Incident radiation containing a plurality of distinct, nonoverlapping spectral regions of wavelengths in the near-infrared range is used to irradiate the sample. Diffusively reflected radiation emerging from the sample is detected, and a value indicative of the concentration of the analyte is obtained therefrom, preferably using an application of chemometrics techniques. Information obtained from each of the nonoverlapping spectral regions of wavelengths can be cross-correlated to remove background interference. |
