| IDEMO-2 | Stabilizing Digital Holography Using Events Ittetsu Uchiyama1, Chihiro Tsutake1, Keita Takahashi1, Toshiaki Fujii1 1. Nagoya University (Japan) Related IDW ’24 paper: IST5-1L |
 |
| In digital holography, vibrations during acquisition are inevitable and can arise from various sources. These vibrations often cause blurring effects in the acquired holograms, which lead to poor 3D reconstruction. To efficiently remove this blur and in turn, stabilize digital holography, we integrate an event camera into the digital holography system. We use a hybrid event camera that can simultaneously record a hologram and events. Experimental results demonstrate that leveraging event data significantly contributes to enhancing fringe patterns and improving the accuracy of 3D reconstruction. | ||

PVG's periodicity structure is achieved within seconds using polarization holography, photoalignment, and self-assembly of LCs. Notably, PVG's periodicity structure is not by etching or nano-imprinting as in surface relief gratings, nor by phase separation in holographic polymer-dispersed LC-type volume bragg gratings. Moreover, multilayer stacking, spatial slant angle variation, and film-thickness variation for optimal performance have been demonstrated with PVG WG in Meta Reality Labs Research in Redmond, Washington, USA. You’re invited to check out our latest PVG waveguide demo in IDW '24. | ||

 |
| The visible range of conventional digital signage using aerial display is limited to the area in front of the digital signage due to the principle of aerial display, which causes a decline in advertising contact rates. We demonstrate cylindrical aerial display with all around view using AIRR. By rotating the AIRR structure at high speed and connecting the afterimages of the aerial images by time-division display, a cylindrical aerial image can be realized. The figure shows an aerial image displayed by a demonstration display. The observer can view a 54-degree (approximately 15%) of the cylindrical aerial image | ||

 |
| A novel hollow-face illusion is demonstrated. Rotation of a face-like image is perceived when the viewing angle is changed horizontally. Our demonstration is realized by changing the depth position of parts of face-like image in the arc 3D display. Although the face-like image with inverted concave depth position has no 3D features like real face or mask, the face rotation can be perceived by observer movement. When the observer is moved, face-like image is perceived as if rotating in hollow-face illusion regardless of the perceived depth positions of the facial parts. | ||

| A digital cosmetic system that does not glare to its users is demonstrated. Our system is a kind of augmented reality (AR) display without glasses. An aerial makeup image is formed on the user’s face by placing the face at the position of the aerial image formed with aerial imaging by retro-reflection (AIRR). This method does not cause glare to the user because the light is spread over a large beam splitter in the AIRR optical system. In this demonstration, a pattern of different shapes is sequentially projected onto the user's face. | ||
| IDEMO-41 | Object Measurement with Floating Aerial Scale Based on AIRR Azu Murakami1, Ryosuke Ichikawa1, Hiroki Takatsuka1, Shiro Suyama1, Hirotsugu Yamamoto1 1. Utsunomiya University (Japan) Related IDW ’24 paper: FMCp1-12 |
 |
| A novel measurement method is demonstrated. Our method utilizes aerial imaging by retro-reflection (AIRR) for an aerial scale floating in mid-air. The aerial scale can be placed at the same position of a target object. In the measurement, we capture the object and the aerial scale in a single shot. The size of the object is obtained from the captured image. Thus, the measurement is completely non-contact. The proposed method is useful for measurements of size of a moving 3D object, a fluffy 3D object, and a living animal that is moving three-dimensionally. | ||

 |
| We introduce aquatic displays that project images in water. We exhibit two types of aquatic displays, one is with aerial imaging by retro-reflection (AIRR), and the other using dual lens arrays. These aquatic displays have the advantage of not interfering with water flow or the movement of fish, as they do not require a light-scattering screen. They are expected to be used in behavioral experiments by showing aquatic images to animals, and for signage that can be used underwater. | ||
| IDEMO-43 | Shifting the Front Image to Expand the Viewing Zone of Aerial Depth-fused 3D Display Gaku Shikama1, Takahiro Omoto1, Shiro Suyama1, Hirotsugu Yamamoto1 1. Utsunomiya University (Japan) Related IDW ’24 paper: 3Dp2-8 |
 |
| We demonstrate an aerial depth-fused 3D (DFD) display that shifts the front image. In conventional DFD displays, depth can be perceived only at the viewpoint position where the front and rear images overlap, resulting in a narrow viewing zone for 3D display. In this exhibition, by shifting the aerial front image horizontally, DFD display is performed at viewpoint positions where DFD display normally cannot be performed. | ||
| IDEMO-44 | Bidirectional Rotation Perception of Dark Hole on Curved Surface Due to View Position in Depth-Fused 3D Display Takahiro Omoto1, Shiro Suyama1, Hirotsugu Yamamoto1 1. Utsunomiya University (Japan) Related IDW ’24 paper: PRJ7/3D6-4 |
 |
| Bidirectional rotation perception system by using depth-fused 3D (DFD) image of dark hole on curved surface is demonstrated. DFD display usually lacks a sense of coarse motion parallax reality because the displayed image does not change even if the viewpoint is changed within the 3D display area. The DFD display demonstrated in this exhibition using concave or convex luminance distributions in the front and rear images gives the DFD display the perception of rotation like the hollow face illusion. In this way, a more realistic 3D display can be achieved. | ||
| IDEMO-45 | Edge-Based DFD Display with Aerial Image by AIRR and Floating Edge Image by Arc 3D Display Kyoya Hino1, Kensuke Tamano1, Kazuaki Takiyama1, Shiro Suyama1, Hirotsugu Yamamoto1 1. Utsunomiya University (Japan) Related IDW ’24 paper: FMCp1-15 |
 |
| We demonstrate an edge-based DFD display by fusing an aerial image with AIRR and a floating edge image with an Arc 3D display. The optical system consists of a projector, a light-source display, a beam splitter, a retro-reflector, and an Arc 3D substrate. An observer observes DFD images by overlapping two images from the center of both eyes in the depth direction. Furthermore, this system is an optical see-through display, that is, the background scene is visible behind the DFD image. Since the distance between the two images can be changed, this method can freely express perceived depth. | ||

 |
| A novel aerial information display for both sides is demonstrated. Our demonstration is realized by AIRR by use of striped retro-reflectors and subjective super-resolution display method. The optical system consists of two sets of light sources, retro-reflectors, polarizers, and one beam splitter. Each observer can observe a different aerial image while looking at the other's face. Although the conventional system has a problem that the striped retro-reflectors cause gaps in the aerial image, the gaps in the aerial image are complemented and the entire of content is clearly visible by scrolling the displayed content. | ||
