Abstract
Previous results revealed that the influences, caused by both individual differences an1d measuring environmental factors, would be reduced by using the floating-reference theory (FRT) for diffused reflectance spectra (DRS) -based blood glucose measurement by Near Infrared Spectroscopy (NIRS). The obtained signals could highlight the variation in light intensity which was brought only by the change of glucose concentration. The existing studies on FRT have mainly focused on the diffused reflectance spectra, but rarely involved the diffused transmittance spectra. In this talk, it is our aim to investigate the availability of FRT on the diffused transmittance spectra (DTS) on the basis of Monte Carlo (MC) simulation method. The MC simulations of DTS have been carried out with different glucose concentrations and skin tissue thicknesses. The simulation results show that the floating reference position point of DTS will disappear when the tissue thickness is greater than a certain value. Therefore, the FRT might be applied on thin tissue model for DTS by NIRS.
