発明の名称 (英語) DISPLAY DEVICE AND METHOD FOR DISPLAYING AERIAL IMAGE
発明の概要(英語) A display device (1A) as an embodiment of the present invention is provided with a light source (2), a light branching part (40) for causing first emission light (L1) emitted from the light source to be surface-reflected as first reflected light (L2), a retroreflection part (6) for retroreflecting the first reflected light toward the light branching part as retroreflected light (L3), and a first light shielding part (8) for shielding surface-reflected light (L4) surface-reflected by the retroreflection part toward an observation position of the retroreflected light. The light branching part transmits at least a portion of the retroreflected light.
従来技術、競合技術の概要(英語) BACKGROUND ART
In recent years, communication, broadcasting, entertainment, art, including medical and the like in the field, using the space or environment, such as special glasses is not applied to the visible image can be displayed on the display a three-dimensional space in the air has been attracted attention. Within the three dimensional space as described above as one of methods for images are displayed, using retroreflective (Aerial Imaging by Retro-Reflection: AIRR) airborne display has been known (for example, see Non-Patent Document 1).
For example, to Patent Document 1, as an example of a configuration that suppresses the number of parts, the passage of light from the object (light source) is placed on the beam splitter, and transmitted or reflected by the beam splitting device and the passage of light from the object are placed in the retro-reflective means is a display device is disclosed. In the display device in Patent Document 1, a beam splitting device is, the opening in the opaque surface mounted.
