Int his article, we analytically present the influence of the systematic error due to the theoretical assumptions on the blood oxygenation determination using a 'phase-only' dual-wavelength phase-modulation spectroscopy (PMS). To approach an accurate quantification of hemoglobin saturation, an empirical method to experimentally acquire the initial phase-shift value in oxygenation quantification form PMS data is investigated on blood-perfused phantom. Our results show that the quantification error of blood oxygenation determination can be substantially compensated by using the acquired (theta) 0(lambda ) method and is confirmed to be less than 10 percent by comparison with the measured results of the Pt electrode.
