The present invention relates to an optical coherence tomography device and an optical coherence tomography method using same for capturing the cornea and the retina of the eye by using light sources in respectively different wavelength ranges. According to the present invention, included are two light sources, a first interferometer and a second interferometer for generating respectively different interference patterns by the light outputted from each of the light sources, and interference pattern detection means for detecting an interference pattern occurring in each interferometer.
