Comparison between spectral optical coherence tomography and the FFT-based impulseresponse reconstruction method in the transmission configuration

We present a comparison between the well-known spectral optical coherence tomography (SOCT) technology and the fast-Fourier-transform-based (FFT-based) impulse-response reconstruction method (FIRRM), which we developed- both in the transmission configuration. It is shown that, since the transmission configuration requires relatively long interferometers, the SOCT measurements are less stable than those of the FIRRM, as seen in the impulse-response reconstruction of the two methods. The FIRRM results show much better agreement with theoretical predictions.
