We demonstrate the feasibility of estimating hemoglobin oxygen saturation ( Sa O 2 ) from erythrocytes over a visible wavelength band using high-resolution spectroscopic optical coherence tomography (SOCT). We take SOCT spectra from individual cells on in vitro human blood phantoms and calculate Sa O 2 by fitting the spectra to an analytical model. We also use diffusive spectroscopy (DS) measurements, which is validated by direct measurement of oxygen partial pressure, as a comparison. The result shows a reliable linear association between the Sa O 2 derived from SOCT and the DS measurement, indicating this methodology has potential on in vivo applications to evaluate blood oxygenation.
