A display technique capable of displaying special images. A display includes an image display layer and a mask layer. The image display layer includes one or more colored portions, and displays a transmitted light image corresponding to the one or more colored portions when illuminated with white light. The mask layer includes a transparent material layer having a first major surface and a second major surface, and the first major surface includes one or more regions each composed of first and second strip-shaped parts alternately arranged in a width direction. The second strip-shaped parts are provided with a relief structure. A portion of the mask layer corresponding to at least one of the one or more regions conceals a portion of the transmitted light image corresponding to the second strip-shaped parts.

A laminated glass includes first and second glass plates. First and second interlayers are arranged on the first and second glass plates, respectively. The first and second glass plates are arranged so as to have the first and second interlayers face each other. An enclosing layer is arranged between the first and second interlayers. The enclosing layer includes a functional member having a sidewall, and a dummy layer arranged on the sidewall, the functional member including one or more transparent layers. The functional member has a thickness of 200 μm at a maximum. The dummy layer is made of a thermoplastic resin.

A method for manufacturing an article that records a holographic image when photographed or videotaped but otherwise not visible to the naked eye. The article, such as a basketball, includes at least a layer of polyurethane leather that is reflective and is illuminated on photographic media when imaged. The illuminated or holographic image may be seen and displayed on a digital device, such as a social media platform.

A stereoscopic image forming device in a ring-shape or a shape partly using a ring-shape when viewed from above and a manufacturing method of the same, in which a plurality of first vertical light reflective members 12 are provided in one side of a transparent flat plate material 16 and a plurality of second vertical light reflective members 14 are provided in the other side of the transparent flat plate material 16. The first vertical light reflective members 12 are arranged radially around a reference point X, whereas the second vertical light reflective members 14 are arranged concentrically around a reference point Y overlapping the reference point X when viewed from above. The first vertical light reflective members 12 and the second vertical light reflective members 14 orthogonally intersect each other when viewed from above.

An aerospace mirror having a reaction bonded (RB) silicon carbide (SiC) mirror substrate, and a SiC cladding on the RB SiC mirror substrate forming an optical surface on a front side of the aerospace mirror. A method for manufacturing an aerospace mirror comprising obtaining a green mirror preform comprising porous carbon, silicon carbide (SiC), or both, the green mirror preform defining a front side of the aerospace mirror and a back side of the aerospace mirror opposite the front side; removing material from the green mirror preform to form support ribs on the back side; infiltrating the green mirror preform with silicon to create a reaction bonded (RB) SiC mirror substrate from the green mirror preform; forming a mounting interface surface on the back side of the aerospace mirror from the RB SiC mirror substrate, and forming a reflector surface of the RB SiC mirror substrate on the front side of the aerospace mirror. Additionally, the method can comprise cladding the reflector surface of the RB SiC mirror substrate with SiC to form an optical surface of the aerospace mirror.
