Abstract
An augmented reality device includes two optical combiners configured to correspond to two eyes of a user respectively, each of the two optical combiners comprising an internal surface for reflecting light from the image source to a respective eye of the user, wherein the internal surface is a freeform surface with a surface function that is based on an XY-polynomial including at least one multivariate monomial; an image source positioned above the eyes of the user to emit light onto the optical combiners, wherein the image source comprises two active displaying areas which are on two different planes; and a housing structure configured to maintain relative position and orientation of the optical combiners and the image source.
