Apple's Holographic Display Concept

Why Apple Will Turn to Holograms - Businessweek

[...] here is a prediction—Apple devices will soon project holograms like you’ve never seen. This is not mere speculation, but insight based on Apple’s patents, recent acquisitions, and the business imperative to do something to break free of the tablet clutter.

In November 2010, Apple patented a three-dimensional display system that would “mimic a hologram” without requiring special glasses. The patent narrative is fascinating, noting that one current market gap in screen technology is the ability of a device to project stereoscopic 3D images to multiple viewers at the same time.

Apple patents 3D display with holographic images and Kinect-like gesturing - SlashGear

Under this patent, the virtual items in this 3D space can include nearly any object that can be grasped and manipulated within the virtual space, including sheets of paper, hand tools, paint brushes, pencils, pens, knives, scissors, etc. Any manipulation of these virtual objects or controls can also be further reinforced with audio feedback, such as clicking sounds for virtually rotating knobs, flicking switches, or pressing buttons.

Apple also proposes using 3D imaging technology to track the movements of multiple viewers and the positions of their eyes so that the direction the image is deflected by the screen can be subtly adjusted to ensure the picture remains sharp and in 3D. The patent claims this technology would also create images that appear to be holographic because of the ability to track the observers movements.

"As well as watching 3D movies, Apple's system would have a ton of applications in science, engineering, design and education, while 3D iPhones and iPads would be killer.


"It's easy to imagine things like amazing 3D textbooks and instructional videos. 3D gaming on an iPad would be an incredibly immersive gaming experience."

Apple said it does not comment on patents.

TeleHuman & BodiPod: Telepresence with Holographic 3D Telepods

Holographic 3D Telepods May Revolutionize Videoconferencing -- Science & Technology -- Sott.net

A Queen's University researcher has taken inspiration from Star Trek to create an other-worldly way to meet with one another. Using a series of strategically placed projectors and Microsoft Kinect image sensors, Dr. Roel Vertegaal and his team at the Human Media Lab in Canada have created a human-scale 3D videoconferencing pod, allowing people in different places to meet with one another, just as if they were in the same room at the same time.

While the technology may seem like it comes from a galaxy far, far away, it's not as complicated as most would think. Dr. Vertegaal and his team used mostly existing hardware – including an array of Microsoft Kinect sensors, a 3D projector, a 1.8 metre-tall translucent acrylic cylinder and a convex mirror.

The research team, also consisting of John Bolton, Kibum Kim, Peng Wang and McGill Prof. Jeremy Cooperstock, used the same Pod to create another application called BodiPod, which presents an interactive 3D anatomy model of the human body. The model can be explored 360 degrees around the model through gestures and speech interactions.

When people approach the Pod, they can wave in thin air to peel off layers of tissue.  In X-ray mode, as users get closer to the Pod they can see deeper into the anatomy, revealing the model’s muscles, organs and bone structure. Voice commands such as "show brain" or "show heart" will automatically zoom into a 3D model of a brain or heart.

Digital Holographic Microscopy (DHM) Reveals Brain's Inner Workings

Holograms reveal brain's inner workings | Health | EarthSky
http://earthsky.org/health/holograms-reveal-brains-inner-workings


  • Scientists have discovered a way to observe living neurons without damaging them – in 3D and with up to 50 times greater resolution than before. The technique, using digital holographic microscopy (DHM), is non-invasive and can create imagery of hundreds of neurons at once. DHM has the potential to streamline drug studies involving neurodegenerative diseases such as Parkinson’s and Alzheimer’s, because researchers can test new drugs more quickly and in greater numbers than before.

     The research team, from Switzerland’s École Polytechnique Fédérale de Lausanne (EPLF) and Centre Hospitalier Universitaire Vaudois (CHUV), included neurobiologists, psychiatrists, and advanced imaging specialists. Results of their collaboration appear in the August 17, 2011 issue of The Journal of Neuroscience.

  • “DHM is a fundamentally novel application for studying neurons with a slew of advantages over traditional microscopes,” explains Pierre Magistretti of EPFL’s Brain Mind Institute and a lead author of the paper. “It is non-invasive, allowing for extended observation of neural processes without the need for electrodes or dyes that damage cells.”

     Senior team member Pierre Marquet adds, “DHM gives precious information not only about the shape of neurons, but also about their dynamics and activity, and the technique creates 3D navigable images and increases the precision from 500 nanometers in traditional microscopes to a scale of 10 nanometers.”

  Typical optical setup of DHM.

  • Digital holographic microscopy (DHM) is digital holography applied to microscopy. Digital holographic microscopy distinguishes itself from other microscopy methods by not recording the projected image of the object. Instead, the light wave front information originating from the object is digitally recorded as a hologram, from which a computer calculates the object image by using a numerical reconstruction algorithm. The image forming lens in traditional microscopy is thus replaced by a computer algorithm.

  • DHM ® , the Digital Holographic Microscopes
    For the first time, microscopes combine nanometric resolution, real-time and non-invasive three dimensional observation. These new instruments, based on a revolutionary patented technology called "Digital Holographic Microscopy" (DHM), are developed, manufactured and commercialized by Lyncée Tec SA.

  • Real-time monitoring
    The DHM system is an ideal tool for real-time cell monitoring because it allows, from a single image acquisition, non-invasive high-resolution imaging of living cells in their natural environment without use of a contrast agent. The real-time imaging (up to 15 fps for a 512x512 pixels image) and the postponed reconstruction (up to 10'000 fps by using high-acquisition rate camera) make the DHM instrument a system well suited for the dynamic analysis of morphological modification of cells due to natural or artificial stimulations such as drugs, electrical or thermal stimuli.
    For example, neuron cell swelling induced by hypotonic stress was studied by the Brain Mind Institute (EPFL, Switzerland).

Hologram TV is Coming

Times Online

Watch closely, ‘Star Wars’ hologram TV is coming

THREE-DIMENSIONAL television may be the latest in home cinema, but it will soon seem so 2010. Scientists are already planning its successor — holographic television.

On a holo-TV, images will be projected into the middle of a room as a “cloud” that can be enjoyed from every angle without 3-D glasses.




Forget 3D glasses! 'Star Wars' hologram TVs will put you IN the action

[...]

Holo-TVs will resemble a large book laid out on the floor, according to Sony engineers. Lasers will then project a 'cloud' of images that will appear to float in the middle of the room and can be enjoyed from every angle WITHOUT 3D glasses.

It may sound like an implausible technology more suited to Star Wars films than real life, but industry leaders are taking it very seriously indeed.


Japan proposes holographic 3D broadcasts for 2022 World Cup

While we're limited to merely 3DTV depictions of the 2010 World Cup, Japan is letting its freak flag fly in a proposal to host the 2022 matches with a concept envisioning matches captured by 200 HD cameras, then projected as fully 3D images onto real fields in other countries.

Debut of a Live 3D Teleconferencing system at ASC2008 on Dec. 1, 2008 by the Graphics Laboratory from the University of Southern California's Institute for Creative Technologies. The participant is scanned in real time in 3D using structured light and the geometry and texture is transmitted in real time to a spinning mirror with high speed video projection, resulting in a hologram-like 3D image of the person speaking. For more information see:
Rendering for an Interactive 360º Light Field Display
The system works by projecting high-speed video onto a rapidly spinning mirror. As the mirror turns, it reflects a different and accurate image to each potential viewer.
The display is:

• autostereoscopic - requires no special viewing glasses
• omnidirectional - generates simultaneous views accomodating large numbers of viewers
• interactive - can update content at 200Hz

InPhase Introduces 300GB Holographic Storage

InPhase Technologies has just unveiled its 300GB removable storage drive that uses holographic technology to record data at high densities. The 12-centimeter plastic discs can be read by a special drive, called the Tapestry. InPhase has been working on the device for eight years now, and it seems that the Tapestry is ready to roll out.

What is Holographic Storage?

Recording data

Light from a single laser beam is split into two beams, the signal beam (which carries the data) and the reference beam. The hologram is formed where these two beams intersect in the recording medium.
Recording
Reading data

In order to read the data, the reference beam deflects off the hologram thus reconstructing the stored information.
