Abstract: In the OCT apparatus, the reference mirror is a mirror having a multi-layer structure having at least two planes and includes a first plane and at least one second plane having a height difference corresponding to ¼ length of a central wavelength of the light source or an odd multiple of ¼ length with respect to the first plane such that beams reflected by the planes have a phase shift corresponding to a half wavelength or an odd multiple of the half wavelength. Since a bandwidth of a light source is not increased, large broadband performance of optical parts is not required and neither is dispersion compensation of the path in each coherence arm. Therefore, the OCT apparatus using the reference mirror can be applied in industries that require various precise thick film techniques through the tomography image having the remarkably enhanced contrast in the depth direction.
