摘要： An augmented reality (AR) optical device comprises an AR optical system configured to generate an AR image and lay the AR image over an actual environment image perceived by a user and a light attenuator disposed in a direction along which the AR optical system is optically exposed to an actual environment and configured to attenuate a brightness of the actual environment image.

摘要： A multi-focal optical device comprises an image output unit outputting optical information, a linear polarizer uni-directionally polarizing the optical information, a first light reflector including a first polarizer transmitting light only in a first direction and reflecting the light transmitted through the first polarizer, a second light reflector including a second polarizer transmitting light only in a second direction perpendicular to the first direction and reflecting the light transmitted through the second polarizer, a light splitter splitting the optical information transmitted through the linear polarizer into the first light reflector and the second light reflector and reflecting the optical information reflected by one of the first light reflector or the second light reflector to allow the reflected optical information to form one focus, and a controller configured to control the linear polarizer to vary a direction of polarization of the linear polarizer.

摘要： 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.

摘要： An augmented reality optical device includes an image generator receiving a preset wavelength range of light reflected by an affected part and generating an affected part image, an image output unit outputting a visible wavelength range of light corresponding to the affected part image, a first mirror unit reflecting the light output from the image output unit, a lens unit focusing the reflected light, a beam splitter reflecting a preset wavelength range of light incident from the outside in a preset direction and transmitting a portion of an incident visible wavelength range of light to a user's pupil (or in the preset direction) while reflecting another portion of the incident visible wavelength range of light in the preset direction (or to the user's pupil), and a second mirror unit re-reflecting the preset wavelength range of light reflected by the beam splitter to the image generator.
