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.

Abstract: Disclosed is a polarization sensitive optical coherence tomography apparatus and control method thereof. According to the polarization sensitive optical coherence tomography apparatus and control method thereof of the present invention, the local phase delay value of each layer of a multiple of layers using Jones matrix for a birefringent material having the multiple of layers where each layers optical axis is random based on a polarized signal detected in an optical detector may be calculated. According to the present invention, a skin aging level can be accurately examined by obtaining an accurate accumulated phase delay value for a multiple of layers of birefringent material having a random optical axis.
