Abstract

In vivo absorption and scattering spectra of different human tissues were obtained using a system for time-resolved reflectance measurements in the wavelength range from 610 nm to 1010 nm, every 5 nm. The system is based on a dye laser and a Ti:Sapphire laser as light sources and an electronic chain for time-correlated single-photon counting for detection. Measurements were performed on the breast, the arm, the abdomen, and the forehead of healthy volunteers. The scattering spectra decrease upon increasing the wavelength, while the absorption spectra show the spectral features of oxy- and deoxyhemoglobin, water, and lipids.
