Holograms: More
Than Neat Stickers Response
Movies
have become one of the biggest industries in a short period of time. From black
and white images without sound, to realistic and 3D images on big projectors. Now
in 2015, we have come from big TV boxes to giant flat screens that weigh like
paper and use water instead of mechanical engineering inside. Now that we’ve
come almost a century of basic TV, we have come to the age of Holograms. A
technological advancement from 2D images on a flat screen to real life 3D figures
in midair.
A
Hologram is a three dimensional image formed by the interference of light beams
from a laser or other coherent light source. The Hologram was put in the mind
by the physicist Dennis Gabor. Gabor was trying to piece back together an
electron telescope when the thought hit him. Gabor then further went into the
study of holograms that led him to win a Nobel Prize in 1971 in physics. Further
testing didn’t come until 1962, when two students from the University of
Michigan were playing around with the theory of Gabor, when they produced the
first laser hologram from physical objects such as a train and a bird.
Holograms are now in full
use all over the country and in the world. They are used in museums for
displays on many works of art. Though this was just the beginning of the history
of holograms, with further testing after the horse play with the Gabor
theories, further researchers comment, can a hologram hold the code for memory?
Technology based companies are in the research of holographic memory. They have
concluded that a holographic memory can hold up to one terabyte, more than the
average computer and takes about 95 percent less space than the computer hard
drive. Holographic imagery turns out to
be way easier and very efficient and hold a promise for the future of
technological innovation on memory and screens. Though as much as the holographic
memory turns out to be, there are lots of cons to it. For example, when setting
up the holographic memory, two lasers are set up, one a spatial-light modulator
and one to the specific region of the crystal, where the special data is going
to be read. Then it the signal it send will create the digital image of the
memory. These lasers, however, have to be precise and the accuracy is
inevitable to have a successful reading on your holographic memory. With all
these factors, holographic is turning out to be temporary. Though researchers
are taking the challenges in these upcoming years to figure out how to outcome
these factors.
In which case, although holograms
are innovative and are becoming a very successful project, there are still many
decades of in depth research. Holograms are a technological advancement that is
in the making and will for sure be the next big things in the film industry,
for which we all look forward to.
