Abstract :
In this paper, we propose and investigate a technique to deduce hemoglobin oxygen saturation (SO2) variation image using Spectroscopic Optical Coherence Tomography (OCT). The technique is based on Morlet wavelet transformation and make use of the different absorption properties of hemoglobin (Hb) and oxyhemoglobin (HbO2) around 800 nm. In order to test the technique, we combined three superluminescent light emitting diodes (SLED) together in a Fourier Domain Common Path OCT (FD-CP-OCT) set-up. The result using chicken embryo in vivo shows that we are able to obtain highly localized oxygen saturation variation.
