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 present invention provides an artificial fireplace for displaying an artificial fire pattern. The fireplace comprises a housing, defining an interior and comprising at least one opening to allow a line of sight into the interior, a semi-transparent mirror, which is arranged in the interior and which comprises a first side, facing the opening, and an opposite second side, facing away from the opening. The fireplace further comprises a first display device, which is arranged in the housing and which is configured to display a first video of flames, towards the first side of the semi-transparent mirror, and a second display device, which is arranged in the housing and which is configured to display a second video towards the second side of the semi-transparent mirror. The semi-transparent mirror is arranged to at least partially reflect the first video of flames at its first side and to at least partially transmit the second video at its second side, in order to recombine the first video of flames and the second video into the artificial fire pattern, such that the artificial fire pattern is visible along the line of sight.

摘要： An optical structure surface including a plurality of display region groups including a first display region group and a second display region group. In each display region group, an azimuth angle is formed between a projection direction and a reference direction, and a plurality of reflective surfaces belonging to the display region produce an image. A plurality of display regions include a set of display regions whose azimuth angles are different from each other, and the plurality of display regions display an image unique to the display region group in a display direction by a plurality of reflective surfaces of each of the display regions. The display directions of the first display region group and the second display group are different to provide a different brightness to their respective images, in the respective display directions of the images.

摘要： An optical device has a light guide plate that guides light in a plane parallel to an emission surface thereof, an optical deflection surface that deflects light entering the light guide plate from a light source that faces a plane parallel to at least the emission surface or the surface opposite the emission surface, so that the light travels along the light guide direction of the light guide plate, and a plurality of light focusing portions. Each of the light focusing portions includes an optical surface whereon the light deflected by the optical deflection surface and guided by the light guide plate is incident, and which causes the emission surface to output emission light that converges substantially on a convergence point or convergence line in a space, or that radiates substantially from a convergence point or convergence line in a space.

摘要： Augmented reality glasses can include a first laser, a second laser, and a scanning mirror. The augmented reality glasses can also include a first polarization selective reflector and a second polarization selective reflector. The first polarization selective reflector is arranged to receive light from the first laser and reflect light received from the first laser at a first angle to the scanning mirror, and the second polarization selective reflector is arranged to receive light from the second laser and reflect light received from the second laser at a second angle to the scanning mirror.

摘要： An image display apparatus mountable on a mobile object includes an image light generator and a transmissive member. The image light generator is configured to generate image light and emit the image light to a transmission and reflection member mounted on the mobile object. The transmissive member is disposed in an optical path of the image light between the image light generator and the transmission and reflection member. The transmissive member is configured to transmit the image light from the image light generator. The transmissive member has a cross section with a predetermined curve, the cross section being orthogonal to a predetermined direction inclined with reference to a virtual plane orthogonal to a horizontal direction of the mobile object.
