20 Medical Applications of NIR Spectroscopy

Fig. 20.11 Temperature dependency of in vivo skin diffuse reflection NIR spectra measured by a tipthermostated fiber-optic probe of type I (a) and for a tissue phantom without blood micro-circulation
effects, showing clearly the temperature dependency of the water constituent (b); reproduced in part
from [27] with permission of SPIE—The International Society for Optics and Photonics
For further information on these developments using photoplethysmography with
regard to blood glucose sensing, the reader is referred to our recent review [28].
20.3.2 NIR Spectroscopy of Skin–Optical Data for Photon
Migration Modeling
The diffuse radiation transport in biological tissues can be modeled by using different
mathematical tools providing an understanding, e.g., of the probed tissue volume
