New ultrasound research creates holographic objects that can be seen and felt

Haptic feedback has become a common feature of recent technology, but such systems usually rely on stimulation of parts of the user’s body via direct mechanical or acoustic vibration. A new technique being developed by researchers at the University of Bristol promises to change all of this by using projected ultrasound to directly create floating, 3D shapes that can be seen and felt in mid-air.Read More

MIT develops glasses-free 3D projector as a "practical alternative to holographic video"

The 3D format has had something of a renaissance in recent years, but the technology still has some way to go before the potential of "real-life" multiperspective 3-D can be realized. The Camera Culture group at the MIT Media Lab is developing a new 3D video projection system that doesn't require glasses and provides different users different perspective angles of the same object. The team sees it not as a final answer, but as a transitional system that sits between current technologies and true holographic video.Read More

Smart holograms can test for and monitor diseases

A team of interdisciplinary researchers have created "smart" holograms that can monitor health conditions or diagnose diseases, by changing color in the presence of disease indicators in a person's breath or bodily fluids. When developed into a portable medical test, these responsive holograms could make testing for medical conditions and monitoring one's health very easy, the scientists claim. Read More

Fabricated nanoantennas used to produce high-resolution holograms

Holography is one of the more dramatic forms of photography, in which a three-dimensional image is stored on a photographic plate in the form of interference fringes. Researchers at Purdue University in Indiana have developed a different approach, in which a 3D image is stored in a structure of thousands of V-shaped nanoantennas etched into an ultrathin gold foil. The new approach dramatically shrinks the size of a hologram, potentially enabling photonic and plasmonic devices and optical switches small enough to be integrated into computer chips.Read More

Holovision aims at life-size 3D projections

Close on the heels of the 21st century complaint of “Where’s my jetpack?” is “Where’s my holographic projector?”. Nothing spells “future” like having a conversation with someone whose life-size image is beamed into the room. Provision of Chatsworth, California wants to bring that one step closer to reality, with its Holovision life-size holographic projector. The company is currently running a Kickstarter campaign aimed at raising US$950,000 to fund the development of new technology for the projector, with hopes of unveiling it next year.Read More

New technology from MIT may enable cheap, color, holographic video displays

Researchers at MIT’s Media Lab have developed a new form of holographic projector that may enable the introduction of practical color 3D holographic video displays as well as higher-resolution 2D displays with lower power consumption. The new projector is built using principles of guided wave optics to construct the spatial light modulator (SLM) that is the heart of digital holography. The MIT holographic projector, which contains an SLM costing US$10 to fabricate, provides 3D images at 30 frames per second (fps) with a resolution similar to that of a standard-definition TV.

MIT develops new glasses-free 3D TV technology

Though 3D movies have been around for a while, the experience of visiting a cinema to catch the latest blockbuster is dampened by unwieldy glasses and the limitation of only one fixed perspective being offered to all. The illusion of depth is present, but this is far removed from the hologram-like, multiple-perspective experience which would truly wow movie-goers. MIT's Media Lab’s Camera Culture group proposes a new approach to 3D images that promises glasses-free multiple-perspective 3D. Perhaps best of all though, MIT's technique uses inexpensive existing LCD technology, clearing the way for the tech to be implemented into TV's. Read More
