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.

Near-eye augmented reality device

An optical object positioning apparatus including an optical element, a light sensor and a processing unit and a positioning method thereof are provided. The optical element includes a first surface and a second surface opposite to each other and perpendicular to a first axis, and has at least two light-passing regions. Light beams from an object to be positioned pass through the light-passing regions from the first surface to the second surface. The light sensor and the optical element are spaced by a predetermined distance on a direction of the first axis. The light sensor senses the light beams from the light-passing regions to generate at least two light-sensing signals. A distance between the object and the optical element is positively correlated to the predetermined distance. The processing unit receives the light-sensing signals and positions the object according to the light-sensing signals and the predetermined distance.
