How Hologram Technology Proves To Be Beneficial?

Hologram technology may have developed by leaps and bounds but it is not yet possible for holographic volumetric display to produce arbitrary scenes. If you nurture the idea that holography is more of a 3D photography then it is a regret to say that you are having a misconception about holography. Holography is about a technology that involves interference of two light beams resulting to a light field of random pattern of varying intensity. Then once the hologram is illuminated one is able to see the objects in the hologram though they are not present there any more. As a recording material, there are a variety of materials available.


Benefits of hologram technology

As far as 2D projection of images are concerned, the hologram technology has bought about the advent of holographic projection. Moreover, the advent of holographic projection has brought about a nice alternative to other conventional processes of image projection. The recent hologram technology is even used in various video projectors as they require very few components and can be made very small. As a result the projectors made on the basis of hologram technology provides the option of being integrated in a laptop or a mobile phone.


Latest hologram technologies

Hologram technology is also used in holochambers. Holochambers are actually small room that is fitted with holographic projectors whenever there is a need to produce a realistic image onto the ceiling and walls. However, previously holochambers used to face some problems due to the limitations of hologram technology. The limitations of hologram technology barred the creation of any character but recent development like the ‘internal partitioning’ has made hologram technology equipped enough to overcome all those hurdles. However, the best development in hologram technology is the invention of holomatter in holochamber. The holomatter is a solid matter and is a product of holochamber energy grid along with computer driven tractor beams, which are highly articulated. These matters are usually used by the holochambers whenever there is a need to create a realistic character within the chamber.


What is 3D Hologram?

Three-dimensional images, better known as 3d holograms are created by capturing a laser light interference pattern on film. Mainly, they are created by interweaving the coated graphics of one complete master image. The special 3d holography effects are created by printing graphics in register on back side of special lens material.

Materials for 3d holograms

The holographic 3d mostly comprises of two main material types. They are heavy gauge and fine gauge. The main distinction between the two is in the viewing distance. The thicker the lens the greater is the viewing distance.

Heavy gauge are used in those applications, which have superior viewing distances. Holographic 3d needs slower printing and finishing methods as the lens thickness restricts on the printing method. While the Fine gauge are used in those applications for closer viewing distances. They can be printed through printing press that allows good economy.

Characteristic Features of 3d holograms

A unique feature of the 3d hologram is the ‘parallax’. The unique term refers to the ability to view a scene and colors from many angles and depths. The colorful effect that comes from microstructures within the hologram often leads to the diffraction of the light striking them.

Another notable feature of 3d hologram is the complex optical patterns. The patterns contain information about the depth and photographic look of the image.

Various types of 3d holograms printing effects


3d hologram flips –  This is regarded as the simplest of all animation effects. Here, an image changes or flips from one image to the next.

3d hologram zoom – This effect allows an image to move closer or farther away in the sequence of animated positions. The effect works best when the background is common through out for all the animated images.

3d hologram Morph –  The Morph effects enables changes of one image to another image, using sophisticated image algorithms.

3d hologram Full Motion Video – This effect uses multiple frames of an action, which shows movement from the beginning till end. This effect is best obtained when the background remains constant throughout the sequence.


What are Holograms?

Holograms are three-dimensional photographic images, developed through photographic projections. They work by creating an image composed of two super imposed two-dimensional pictures of the same object seen from different points.

Unlike Virtual Reality or Augmented reality or 3-D graphics display where the image is projected in a two-dimensional surface and where the illusion of depth is applied, holograms are truly three-dimensional images that do not need special viewing equipments.


How Holograms are made?

The hologram is composed of the interference pattern between the two original images. The hologram is printed onto a set of ultra-thin curved silver plates that are made to diffract light. The diffraction splits multi-wavelength white light into each specific wavelength. When this white light strikes the silver plates, the reflections diffract into each specific color, creating two offset images made up of colors that roughly reflect what the original object looked like. The result is a three-dimensional image which we call hologram.


Categories of holograms

Holograms are categorized into two parts. One is Reflection hologram and the other one is Transition hologram. Reflection holograms use white light or laser light, reflecting off surfaces to create three-dimensional images. Lasers are considered as the main components in holographic equipment. On the other hand, you will find Transition holograms that also create a three dimensional image by utilizing monochromatic light.


Applications of holograms

Holograms have various uses. They have many commercial applications. Some of its applications are:

  • Holograms are used as heads up display in military aircraft.
  • Holograms are used by compact disc players to process light.
  • Holographic images prevent the use of fake credit cards.
  • They are used in non-destructive testing of specimen in laboratories
  • Bar codes in store check out counters uses rotating computer-generated holograms called holographic scanners
  • Nowadays hard drives named HOLOSTORE uses holographic computer memory systems to store lot more information.
