An optical coherence tomographic imaging apparatus includes a first measuring beam and a second measuring beam which differ from each other in center wavelength first adjustment unit for adjusting focusing position of the first measuring beam second adjustment unit for adjusting focusing position of the second measuring beam first detecting unit for detecting an interference light generated from a first returning light and a first reference beam, where the first returning light results from the first measuring beam and second detecting unit for detecting an interference light generated from a second returning light and a second reference beam, where the second returning light results from the second measuring beam reflected or scattered, in which the focusing positions of the first measuring beam and the second measuring beam can be adjusted by the first and second adjustment unit to be at different positions in a depth direction.
