  • Patent number: 11960106
    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.
