A system, in one embodiment, includes an optical coherence tomography (OCT) imaging system having a light source configured to emit light. The OCT imaging system further includes a beam splitter configured to receive the light from the light source, split the light into a first light portion directed along a sample arm comprising a sample and a second light portion directed along a reference arm comprising a reference mirror, receive a first reflected light portion from the sample arm and a second reflected light portion from the reference arm, combine the first and second reflected light portions to obtain an interference signal. Further, the OCT imaging system includes a controller having logic configured to perform an auto-ranging process to match the reference arm with the sample arm.
