Abstract :
Measurement technique of skin moisture based on near-infrared spectroscopy and regression analysis is investigated. Appropriate near-infrared wavelengths are selected by the weight loss experiment with the skin sample in vitro, and absorption spectra measured with the human skin in vivo are evaluated. Water contents of the samples are predicted by the partial least squares method, and the results indicate good agreements to actual values. Absorption spectra collected by contact and noncontact measurements are also discussed.
