Visible-near infrared light and PPG signals for noninvasive blood glucose measurement

This dataset consists of absorbance and PPG signals at 625 nm, 850 nm, and 940 nm detected from the index finger of the subjects’ left hands, and the corresponding reference blood glucose values. There are three output channels for each wavelength, corresponding to three light propagation paths(diffuse reflection at the near end, diffuse reflection at the far end, and transmission).
