The principle of non-invasive optical measurement of tissue oxygenation was described with the special emphasis of near-infrared region. Near-infrared light is rather transparent to the living tissue. The profile of light scattering originated from the red blood cell suspension was measured. Using the picosecond spectroscopy, we measured the time of flight in the red blood cell suspension as well as living tissues. Based on the observations, we concluded that near-infrared imaging is feasible.
