High resolution hemoglobin oxygen saturation level imaging using Morlet wavelet transformed spectroscopic Optical Coherence Tomography

In this work, we use Spectroscopic Optical Coherence Tomography and Morlet wavelet transformation to deduce hemoglobin oxygen saturation in blood sample. The technique makes use of the different absorption properties of hemoglobin and oxyhemoglobin around 800 nm. In order to test the technique, we combined three superluminescent light emitting diodes together in a Fourier Domain Common Path OCT set-up. The result shows that this technique is promising in differentiating blood oxygenation status.
