    A theoretical model for the micron resolution spectral domain optical coherence tomography

    The resolution and effective imaging depth (EID) of spectral domain optical coherence tomography (OCT) are of great importance for visualizing the fine details of biological tissues. To this end, a theoretical model for the micron resolution spectral domain OCT was proposed with both the temporal coherence and the longitudinal spatial coherence considered. Based on the model, the parameters that influence the axial resolution, the signal intensity and the EID can be quantitatively analyzed. Among all the parameters the focusing effect of objective lens affects the signal intensity most due to the fast broadening of the effective point spread function (PSF ...
