    摘要： An aerial image formation device 10 comprising two light control panels 28 each including a molding 21 being produced by using a transparent resin, the molding 21 including, on one surface side thereof, a plurality of straight grooves 18 disposed in parallel at a predetermined interval. The straight grooves 18 each have a trapezoidal cross section and expand on the one surface side of the molding 21, with one side surface serving as the vertical surface 16. In each of the two light control panels 28, an inner surface of each of the straight grooves 18 is covered with a light reflecting material 25 and an anti-reflection layer 27 is formed on a surface of the light reflecting material 25.

    摘要： 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.

    摘要： A compact and portable air floating video display apparatus includes a housing that can be installed in a bottle holder in a vehicle. A video display apparatus, a beam splitter, a retroreflector, a retardation plate, and a plane mirror are provided in the housing. In the air floating video display apparatus, a video light of a specific polarized wave from the video display apparatus is reflected by the plane mirror, transmitted through the beam splitter, and subjected to polarization conversion by being reflected by the retroreflector and passing through the retardation plate. Then, the video light is reflected by the beam splitter and transmitted through the window, thereby displaying an air floating video outside the apparatus.

    摘要： An image generating module and a floating image generation device are disclosed. The image generating module includes an image generation unit and a floating image generation unit. The floating image generation unit having a light axis is disposed parallelly on one side of the image generation unit and includes a light receiving surface and a light emitting surface disposed opposite to each other. The light receiving surface faces the image generation unit. The image generation unit provided an output light for generating a real image outside the light emitting surface. The absolute value of the radius of curvature of the light receiving surface at a position close to the light axis is smaller than the absolute value of the radius of curvature of the light emitting surface at a position close to the light axis. The floating image generation device includes a light source and the image generating module. The floating image generation unit is disposed parallelly on the opposite side of the image generation unit with respect to the light source. The light emitted by the light source passes through the image generation unit to generate a real image.

    摘要： An aerial image forming element 10a used for an aerial image forming device 30 includes a plurality of first and second light reflecting surfaces 12 and 14 respectively formed vertically on the obverse and reverse surfaces of a flat plate-like transparent base member 11a. The plurality of first light reflecting surfaces 12 are placed radially on the obverse surface side of the transparent base member 11a centered on a reference point X existing outside the transparent base member 11a in planar view. The plurality of second light reflecting surfaces 14 are placed concentrically on the reverse surface side of the transparent base member 11a centered on a reference point Y overlapping the reference point X in planar view. The aerial image forming element forms light externally entering and reflected once by each of the first and second light reflecting surfaces 12 and 14 into an image in the air.
