FIELD: augmented reality device.
SUBSTANCE: invention relates to augmented reality devices, specifically to a projection of a virtual image on augmented reality screen. System comprises a screen, a polarization filter, a selective dichroic filter, a first mirror, a second mirror and a display. Polarization filter polarizes the solar radiation passing through the screen. Selective dichroic filter transmits radiation of working range of display, ultraviolet component of radiation and / or infrared component of radiation and reflects all other wavelengths of radiation. First mirror reflects radiation passing through the selective dichroic filter. Second mirror transmits or absorbs the ultraviolet radiation component and / or the infrared component of the radiation reflected from the first mirror, and directs radiation with the remaining wavelengths to the display.
EFFECT: invention enables to eliminate the effect of solar radiation on a display.
