New process allows inkjet printers to produce rainbow holograms

Credit card and banknote-style security holograms are an effective form of anti-counterfeiting technology, as they're very difficult to replicate. Every time a new batch is made, however, a "master hologram" has to be created first, to act as a template. These masters can take days to produce, using complex, expensive equipment. That could be about to change, however, as scientists at Russia's ITMO University have developed a quick-and-easy hologram production method that utilizes a regular inkjet printer.

Sonic tractor beam forms acoustic holograms to lift objects

Last year, researchers at the University of Dundee revealed an acoustic tractor beam that used ultrasonic energy to pull macroscopic objects in. Now researchers in the UK have developed a sonic tractor beam that generates acoustic holograms through the manipulation of high-amplitude sound waves. These acoustic holograms, which can take various shapes, such as fingers, cages and vortexes, are able to pick up and move small objects like polystyrene beads.

3D Cell Explorer produces 3D holograms of living cells in near real time

Swiss company Nanolive has created 3D Cell Explorer, a new technology that creates vibrantly detailed 3D holograms of living cells on the nanometric scale. Created through combining 3D imagery with digital staining, the new microscope offers researchers and hospitals a novel tool to non-invasively peer inside living cells almost in real time, opening up new areas of biological research.

New technique could lead to bigger, cheaper and color-accurate holograms

Microsoft's recent HoloLens announcement has reignited interest in holographic displays, but the current state of affairs suggests that this technology may still be too expensive and limited to become truly widespread. Researchers at Brigham Young University (BYU) and MIT are bridging the gap with a new important step toward the next generation of high-bandwidth, color-accurate holographic video displays that could span the size of an entire room at one tenth the cost of state of the art devices.

Microsoft HoloLens: An AR headset that makes you see 3D holograms in your living room

With virtual reality capturing imaginations during the last couple of years, it's easy to forget about augmented reality. But Microsoft has spent years cooking up its own take on AR, and it's ready to bake the technology into Windows 10. Much like how the Surface was introduced alongside Windows 8, Microsoft has its own holographic AR headset to launch with the new Windows. Read More

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.

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
