So if you haven’t become aware, holograms have been appearing more and more of late as the technology gets refined. Holography or the use of holograms have caught the attention of techies and DIY’ers. Why? The first being it uses a smart phone and it’s really easy to create. I found instructions of how in a wire magazine article recently published;
You’ll need a CD case, an x‑acto knife, graph paper, tape, and a pen—then just follow these steps:
1) First, use the graph paper and pen to measure out a trapezoid that is one centimeter at the top, six centimeters on the bottom, and 3.5 centimeters at the sides.
2) Then using that trapezoid and the x‑acto knife, cut out four identical trepezoids from the clear part of the CD case.
3) Create a pyramid by taping the 3.5cm sides together.
And then you’re done. Follow along with a tutorial video tutorial.
Easy right! And now Samsung just patented for a smartphone screen that’s capable of displaying objects in mid-air, in 3D. Is that right? Yes it is.
Samsungs (jobs at Samsung) next phone the Galaxy S7 may be holographic, the patent was filed back in the second half of 2014. So the patent shows that the icons will be holographic and hover over the surface of the glass. You’ll be able to touch them and the camera would detect the interactions.
Samsung could just be experimenting but that is enough to get excited about. The patent was filed back in the second half of 2014. How far Samsung has come along with this – who knows but I’d love to see it appear in the Galaxy S7 next year.
Then there’s company Aerial Burton having used a plasma laser to float a 3D image in mid-air. At the moment it’s very rudimentary stuff but it shows that light can be viewed without the need to bounce it off a surface. Until now any “hologram” examples have required glass, smoke or water to bounce light from.
The technology uses a 1kW infrared pulse laser which is focused on direct points in the air via a 3D scanner. It can create a picture hovering at specified ranges in midair, molecules in the air are ionized to create plasma. Since these plasma bursts only last a short while the laser needs to pulse in order to keep the area lit.
At present it’s limited in colors but with development, enhanced resolution could mean a future where TVs are replaced by hidden laser projectors that create an image on thin air. You should read our other article about “touchable Holograms here.”
But for now Aerial Burton is focusing on using the holographic projector to create signs for emergency situations. The kit can be car mounted so could prove useful for setting up temporary signs. But what the future holds for this technology remains to be seen.
Try and imagine what the implications of this kind of technology on the media world. Holographic Virtual tour guides in the shape of hummingbirds. Police cars projecting overheard for all to see warning signs of incoming storms or accidents around a corner. Imagine studying an ancient vase inside and out in full three dimensional glory from your smart phone. Do you have your resume ready for these kinds of jobs? Can you think holographically?
