A Fast Monte Carlo simulation based on the spectroscopic optical coherence tomography (SOCT) simulated the back reflection of millions of photons in tissues within tens of minutes. Combined with the short time Fourier transform, the reflection intensity at sixteen wavelengths in visible waveband was achieved. The blood oxygen saturation (SO2) was nonlinear fitted through the different absorption coefficients of the oxyhemoglobin and de-oxyhemoglobin at sixteen wavelengths. We designed a model to simulate human retinal blood vessels and measure retinal oximetry. The results showed that the simulation results were consistent with the theory.
