Holography is a
technique which enables three dimensional images to be made. It involves the
use of a laser, interference ,differaction, light intensity recording and
suitable illumination of the recording. The image changes as the position and
orientation of the viewing system changes in exactly the same way as if the
object were still presents, thus making the image appear three-dimensional.
Holho, currently on
Kickstarter, can be regarded as a more technologically advanced version of
optical illusion gadgets that use two parabolic mirrors to project a 3D image
of an object.
Holho will be available in several versions, from a simple one
that generates a frontal projection to a four-sided pyramid that generates a
complex 3D image which can be viewed from any angle.
The simplest version
is called Holho Naked, designed especially for 10 inch tablets. It creates its
frontal projection with the help of a fold-up mirror that can be used as a case
for the tablet. The Holho Zed functions in a similar fashion, the only
difference being that the tablet is placed at the top and projects the image on
a tilted transparent screen.

A more complex version of the 3D hologram projector is the Holho Three-Face Pyramid
which is exactly what its name says. This version uses the special Holho app to
generate the hologram and is designed specifically for product display or
commercial use.
But the most
impressive of the lot is undoubtedly the Holho Full Pyramid. The gadget is made
of a four-angled mirror with an inverted base sized for tablets and
smartphones. The Holho app generates four images and projects them beneath the
mirrors, creating a full motion 3D video that can be viewed from any angle.
There are several videos already available and the app can be easily used to
create more.
Developers are planning to raise $58,000 on Kickstarter, until
the crowdfunding campaign ends on September 24. Backers can get their own Holho Full Pyramid with a free video for as little as
$28. The special app costs $20 and more videos can be added for $10/each.
What do you think of
the Holho? For the time being, it just seems to be a fun thing to have and a
neat trick party. But what uses could this technology have in the future?
