Abstract: According to one embodiment, an Optical Coherence Tomography (OCT) device includes: a light source; a mirror to reflect a light from the light source; a light receiver to output the light from the light source to skin and receive a light reflected from the skin; a detector to detect an interference signal between the light reflected from the mirror and the light received by the light receiver; an image sensor to convert the detected interference signal into an image signal; a processor to output a second signal by filtering a first signal based on the image signal, calculate an error by using the first signal and the second signal, and output an error-compensated image by compensating for the calculated error; and a display to display the error-compensated image. In this configuration, the OCT device may reduce noise caused by the image sensor, to display a skin image with improved quality.
