Summary:
The purpose of this study is to explore the effect of the wavenumber resolution to the prediction accuracy of the glucose concentration. Then, we propose the glucose concentration prediction method by using partial least square (PLS) regression. We measure the interferogram of a glucose solution by using imaging-type 2-dimensional fourier spectroscopy. For increasing wavenumber resolution, zero-filling is applied to measured interferogram. Then, the interferogram is translated into wavenumber domain by discrete fourier transform (DFT). The PLS regression is applied to the spectrum to predict glucose concentration in aqueous solutions. As the experimental results, the error rate of the glucose concentration prediction reduced from xx% to xx% when xxx zeros were added to original interferogram.
