Star Trek” has been seen and loved by most of the viewers. Those who have seen it must know that the crew of Starship Enterprise is employing their fantasies within a room named as holodeck. The holodeck is nothing, but simply a gigantic holographic projection room that aids the team of crews to experience the projections as if they are playing a video game. In the contemporary scenario, scientists are working so as to develop a latest technology that will allow not only the friends to interact, but also the simulated surroundings, even an individual is thousands miles apart.

No doubt, it is a luck that holographic technology is getting very close to our daily lives and it has been encountered as the future tech.

A Walk Through The History of Hologram:

Before, you understand the terminology; Holographic technology, it is better to identify its origin. “Pepper Ghost” is a well known classic parlor trick which was responsible for the origin of Holograms. This was nothing, but simply the illusion that employed the advantage of a well-maintained mirror in order to project the reflection of ghost in a specific hidden room. Another facile technique, dating back to the 19th century phantasmagoria is still used in some specific regions. Preferably within Disneyland’s Haunted Mansion is the place where the huge Pepper’s Ghost is residing just to make the guests to feel as if they have really entered a haunted ballroom.

There were a few elements of Pepper’s Ghost were employed in order to attain the credit as the most popular hologram of 2012 and it was none other than Tupac Hologram at Coachella. Instead of the so-called hologram, the various people at San Diego projected Tupac on the piece of foil that can be utilized as the angled mirror so as to put them on the stage.

Different Colors of Holography:

Pulse Laser Holography:

Usually, recording a hologram needs an interface pattern of a reference beam as well as scene illumination which needs to be stationary during the time of an interface. This is the compelling reason that drives the hologram to be the traditional form of static sculptures on the vibration secluded tablets. There also exists a pulse laser that is responsible for the production of ultra short flash of light, thus stabilizing the motion and aiding the holograms to be the live subject.

Multiplex and Stenciling Holography:

Multiplexing is the evolving technology which is employed to record the multiple holographic exposures all across the surface of a master hologram. By simply transferring multiplexed master, a finished product in the form of print can be produced where the “virtual windows” on the scene can be fragmented that allow for stereopsis, spatial animation and the depth perception by the parallax s the viewer moves all around. Lloyd Cross made an effort with one amended step of recording the multiplex hologram. He accomplished this by employing the sequence of film frames in order to develop the cylindrical hologram so that image can appear at the center.

Dot-matrix Holograms:

Dot-matrix hologram is simply a printing technique that employs the building up of image with the use of diffractive pixels. Each area used is recorded with the specific geometry that is responsible for the diffraction of light as per the corresponding angle. The illuminating is further deflected into the diversified color spectrum. However, the image is just the form of tiling up of colors that means that the images are bright, but they do not have any 3d depth information. Dot-matrix holograms will be further used as the medium for decorating the “light architecture”.

The tomorrow of Holograms:

As per the contemporary scenario, technology is not ready to be tackled and the implications of the full-scale holographic experience. However, we are very much close than where we were earlier. It is expected that within next ten years, we can have the perfect holograms at the theaters all over and will be watching the crystal clear projections from the tablets.
