Abstract: An augmented reality device includes an image output unit disposed at a preset angle from a horizontal direction to output an augmented reality image of a preset polarization direction, a polarization reflection film reflecting light of the preset polarization direction and transmitting other light than the light of the preset polarization direction, and an optical component disposed on a light path of an image output from the image output unit. The optical component has a preset refractive index and a preset shape. The polarization reflection film is applied on a first surface of the optical component which is positioned farther away from the image output unit.

Abstract: Disclosed herein is a method for quantifying a pigmented lesion using Optical Coherence Tomography (OCT). The method includes (a) irradiating light and receiving an interference signal produced by reflection of the light from first and second boundary layers of a pigmented lesion; and (b) calculating size information of the pigmented lesion using phase information of the interference signal. According to embodiments of the present invention, there is an advantage of allowing calculation of size information of a pigmented lesion using OCT, by increasing a measurement range in the axial direction to which beams are irradiated.
