The Making of a Mona Lisa Hologram

Leonardo da Vinci’s portrait of the Mona Lisa is one of the most readily recognisable works in western art. A group of research institutes have now collaborated to develop an acoustic metasurface-based holography technique that uses a deep learning algorithm to generate and iteratively improve a hologram of the portrait.

NGC Introduces New Security Hologram with Unique QR Codes

Holograms have a long and successful history as a decorative enhancement on coins (see HN November 2022), where, for example, a holographic relief structure is embossed into a resin that coats one side of the coin. But another range of coin applications for holography comes in the shape of security labels that demonstrate the authenticity of the coin.

WiMi Hologram Cloud Builds Ultra-Thin Display System

Holographic displays allow the projection of apparently 3D images in space without the need for special eyewear. They can use a variety of optical methods to create the illusion of solidity and depth, allowing viewers to perceive objects or scenes as if they were real and existing in the physical space before them.

The Holographic Classroom

Holography has a long history as a teaching tool, from the early use as interactive 3D representations of skulls, dental molds and religious relics to the current trend of integration into mixed reality to enhance the teaching and learning process. In this article, we take a look at the evolving role of the technology in teaching and, conversely, at how educators teach students about the technology.

Light Sheet Holography – a New Class of Hologram

A team of scientists and engineers led by Federico Capasso, Senior Research Fellow in Electrical Engineering at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has reported in Nature Photonics a new way of creating holograms using threads of light layered to construct 2D sheets containing tightly controlled arrays of light. These sheets can then be tightly stacked –like a pile of cheese slices – to depict 3D objects.
