Abstract: The disclosure provides an augmented reality (AR) device, a notebook, and smart glasses. The AR device includes a laser source, a spatial light modulator (SLM), and a hologram optical element (HOE). The laser source provides a coherent laser ray. The SLM provides a diffraction pattern solely corresponding to the coherent laser ray. When the SLM receives the coherent laser ray, the diffraction pattern diffracts the coherent laser ray as a hologram in response to the coherent laser ray. The HOE provides a concave mirror effect merely in response to a wavelength of the coherent laser ray, wherein the HOE receives the hologram and magnifies the hologram as a stereoscopic virtual image.

Abstract: An eye tracking device including an optical waveguide component, a light source module, and an eye tracking module is provided. The optical waveguide component has a light-entrance surface and a light-exit surface connecting the light-entrance surface. The light-exit surface has a plurality of micro-structures directly formed on the light-exit surface. The light source module is disposed next to the light-entrance surface and adapted to provide a light beam. The light beam enters the optical waveguide component through the light-entrance surface, and the light beam is emitted from the optical waveguide component through the micro-structures and is transmitted to an eye. The eye tracking module receives a portion of the light beam reflected by the eye and determines a location of the eye based on the portion of the light beam reflected by the eye. A head mounted display is also provided.

Abstract: An eye tracker includes a lens, a beam splitter, a structured light source and an image capturing element. The beam splitter is disposed at one side of the lens. The structured light source and the image capturing element are disposed between the lens and the beam splitter. The structured light source is configured to emit a first light and project to the beam splitter. The first light is reflected to the lens from the beam splitter and passes through the lens to project to an eye. The first light is reflected from the eye to form a second light. The second light passes through the lens and projects to the beam splitter, and is reflected to the image capturing element from the beam splitter. A display is also provided.
