摘要: The reflectance of light from in vivo tissue is described for wavelengths the range 420 to 940 nm, based on photon diffusion theory and experimental results studies 17 subjects. show a minimum peak sensitivity blood pulsations wavelength 510 590 nm. Skin pigmentation seen attenuate rather than altering character modulation spectra. Based model presented, dependence spectra mean fractional volume as well theoretically corroborated by further data at 570 630 At these latter wavelengths, signal-to-noise ratio calculated pulsation signal presence physiological noise. median ratios noise between two are 13.1 7.5, respectively, 93 sites nine These be consistent with theory. >
