The purpose of the present invention is to increase the data processing speed in an SS-OCT and an FD-OCT including the SS-OCT and, in particular, to process large-size data obtained by a receiving unit at a faster speed than the data obtaining speed, reconfigure a tomography image in real time, and provide the reconfigured image to a user. In order to achieve the purpose, according to one embodiment of the present invention, an optical coherence tomography (OCT) is disclosed. The OCT device includes: a light source unit emitting a coherent light; an interferometer unit generating an interference pattern from a sample measured by receiving incident light emitted from the light source unit; the receiving unit receiving the interference pattern emitted from the interferometer unit and converting the interference pattern into an electrical signal; and a processing unit creating an image from data obtained by the receiving unit, wherein the processing unit can group the obtained data into a plurality of data sets and process the plurality of data sets in parallel.
