Claim:
1. A method of operating an optical coherence tomography (OCT) system to identify the presence, location or alignment of one or more lenses of an OCT system, said OCT system including a light source generating a beam of radiation that is divided along a sample path and a reference path, said system having an adjustable imaging window wherein a relative optical path length between the reference arm and the sample arm can be changed to adjust the location of the imaging window, said method comprising: setting the imaging window to be aligned with the likely location of the lens to be identified; obtaining OCT measurement data from said imaging window; evaluating the OCT measurement data to detect the location of signal peaks; comparing the location of the signal peaks with data stored in an optical configuration table with expected lens information to identify the presence, the location, or the alignment of the lens; and, displaying or storing the results of said.
