Abstract
This paper investigates spectral reflectance of blood vessels in a skin tissue phantom. Measured reflectance spectra are slightly influenced by the vessel diameter, depth from the surface, and oxygen saturation state. We discuss a possibility of extracting the information on blood vessels from the reflectance spectra on the basis of color perception using the dominant wavelength in the CIE xy chromaticity diagram with the pseudo-reference white. The results show the usefulness of this method.
