The invention is generally directed to a visual attraction which provides a multi-dimensional audio/video experience in which the three dimensional screens provide for a three dimensional appearing display of two dimensional images in anticipation of and leading up to a reveal event in which the screens rise to expose a view behind the screens. The visual attraction also collects and separates the visitors to the visual attraction by collecting a predetermined grouping of the visitors and processing them through the attraction in a fashion which provides a manageable flow of visitors spaced apart by the length of the show which then passes the group of visitors in the attraction to the remainder of the attraction before collecting and passing through the next group.

A retroreflecting display that enables the formation of a real image in free space includes a first light source that generates a first light output; a first beam splitter module; and a retroreflector module opposite the first light source.

A projection mechanism including a projector emitting projection light by which a game effect image is generated and a projection target mechanism including a projection surface which generates a three-dimensional structure corresponding to a game content, in association with the game effect image generated by projection of the projection light are included.

Disclosed are methods, circuits, optical assemblies, devices, systems and associated computer executable code for estimating for three dimentional imaging. According to some embodiments, there may be provided a projector operable to project a bi-dimensionally coded pattern to provide a first projection of the bi-dimensionally coded pattern and a second projection of the bi-dimensionally coded pattern. The first projection and the second projection may be offset or rigidly shifted with respect to one another, such that a first reflection off an object which is associated with the first projection and a second reflection off the object which is associated with the second projection are provided. A signal corresponding to the first reflection and a signal corresponding to the second reflection may be co-processed.

A persistent image retroreflecting display that enables the formation of a real image in free space includes a first light source that generates a polarized light output; a retroreflector module adjacent a first side of the first light source; a quarter waveplate coupled to the retroreflector module and adjacent the first light source; and a reflective polarizer positioned between the first light source and a viewer of the display.

Embodiments of the present application provide a display screen, wherein the display screen is in a fully-closed or partially-closed housing structure, an interior of the housing structure being configured to provide continuous images with a view angle of 180 degrees to 360 degrees in a horizontal direction; wherein the housing structure includes a cylindrical portion, a side wall of the cylindrical portion being arranged in a smooth arc line or straight line on an axial cross section, and if the side wall of the cylindrical portion is arranged in the arc line, the radius of a circle corresponding to the arc line is greater than a maximum vertical distance from the arc line to an axial line. According to the present application, the audiences feel comfortable in watching and the cost is saved, while a strong sense of immersion is achieved for the audiences.

The present disclosure provides a display system comprising a retro-reflective screen having retro-reflective screen elements that reflect incident light. Each of the retro-reflective screen elements can include three intersecting planes. At least one of the three intersecting planes intersects an adjacent plane at an angle that is 90, with an offset greater than 0. The display system can further include at least one projector that projects the light onto the retro-reflective, which light characterizes an image or video. The retro-reflective screen having the retro-reflective screen elements can reflect the light at a cross-talk that is decreased by at least 10% and/or an intensity that is increased by at least 5%, as compared to a retro-reflective screen with retro-reflective screen elements having planes that each intersects an adjacent plane at an angle of 90, without the offset.

An aerial image display device is capable of changing a depth of a virtual image viewed by an observer without changing a distance between at least one display device and an optical element forming the virtual image. The aerial image display device includes a display device, optical elements, and a reflecting member. The optical elements are installed corresponding to different display regions of a display surface of the display device and sequentially arranged along the display surface in an observation direction of an observer. The optical element is installed obliquely with an angle of about 45 in a X direction when viewed from the display surface of the display device.
