摘要

We studied the axial point spread function of OCT for Gaussian intensity profiles emitted from and coupled back into single mode fibers for signals from a scattering medium. The determined Rayleigh length of the axial point spread function was roughly twice the one measured from the reflection of a mirror. Using the measured point spread function in combination with the single backscatter model allowed determination of the attenuation coefficient of the suspension.
