Abstract: A portable optical coherence tomography (OCT) system includes a main body in which an optical part and a control part of an OCT device are mounted, and which includes a stepped part having a protruding lower front side so that an examinee can load, through the stepped part, an area to be examined, and allows a light source of the optical part to be incident on the area to be examined of the examinee through a hole formed in the front upper side at which the stepped part is disposed; a display part disposed such that a screen for displaying an image captured by the optical part of the OCT device faces a side surface part of the main body; and at least one display movement part connected to one edge of the main body and one end of the display part so that position of the display part moves.

Abstract: An optical tomography device includes a sample optical path system for injecting light, scanned from a light source, into a sample corresponding to biological tissue; a reference optical path system for collecting the light scanned from the light source; and a detection unit for detecting a tomography image of the sample by interfering with sample light, transmitted from the sample optical path system and reflected from the sample, and reference light transmitted from the reference optical path system. The detection unit comprises: a nonlinear crystal which receives the sample light and the reference light and generates nonlinear light having a different wavelength than the sample light and the reference light; and an image sensor which detects a depth direction signal from the nonlinear light.
