DISPLAY FOR AUGMENTED REALITY

An augmented reality device is provided and comprises a waveguide (306); an input diffractive optical element (301) positioned in or on the waveguide (306) configured to receive light from a projector and to couple the light into the waveguide (306) so that it is captured within the waveguide (306)...

Zusammenfassung:	An augmented reality device is provided and comprises a waveguide (306); an input diffractive optical element (301) positioned in or on the waveguide (306) configured to receive light from a projector and to couple the light into the waveguide (306) so that it is captured within the waveguide (306) by total internal reflection; an output diffractive optical element (304) positioned in or on the waveguide (306) configured to couple totally internally reflected light out of the waveguide (306) towards a viewer; and a returning diffractive optical element (307, 309, 312) positioned in or on the waveguide (306) configured to receive light from the output diffractive optical element (304) and to diffract the received light so that it is returned towards the output diffractive optical element (304).
