Abstract
A near-eye augmented reality device includes an imaging unit including a plurality of imaging portions having birefringence and positive diopter, a lighting unit, and a polarization-control unit. The lighting unit is spaced apart from the imaging unit, and includes a base plate and a plurality of pixel modules. The base plate has a first surface proximal to the imaging unit, and an opposite second surface. Each of the pixel modules is operative to produce an imaging light directed towards the imaging unit. The polarization-control unit is operative to control polarization states of the image light and an ambient light.
