Abstract
We found that the bandwidth in the formula calculating the depth resolution of OCT is usually not the same as the bandwidth of the light source; the effective spectral profile for the interfering signal is determined by the dot product of the electric vectors of the light field in the two interfering arms. We thus introduced a new concept: the effective bandwidth in spectraldomain OCT (SD-OCT). Through theoretical and experimental analyses we found that the effective bandwidth is a function of both the polarization matching conditions (PMC) and the path length difference (PLD) between the sample and reference arms.
