(Hologram Technology) This is a research based on an extreme anticipated technology of future and is rising day by day. Hologram technology is making up its roots strong in VFX and entertainment fields. But its roots of origin is hidden, which makes it eligible for research. This research paper will focus on the history of holography, what holography really is, its scope in future, how can we make hologram at home and much more…
History of Hologram Technology
Holography is established in 1947, when British scientist Denis Gabor developed the theory of holography while working to improve an electron microscope. He named the term hologram from the Greek words ‘holos’, meaning “whole,” and ‘gramma’, meaning “message”. Further development in the field was blocked during the next decade because light sources accessible at the time were not truly “coherent”. The barrier was resolved in 1960 by Russian scientists ‘N. Bassov’ and ‘A. Pokhorov’ and American scientist ‘Charles harry’ with the invention of the laser, whose pure and intense light was ideal for making holograms. In 1972 Loyd Cross established the integral hologram by uniting white light transmission holography with conventional cinematography to produce moving 3D images. Holographic artists have significantly increased their technical understanding of the discipline and now contribute to the technology as well as the artistic process. The art form has become global, with major displays being held throughout the world.
Functioning of Hologram Technology
Consecutive frames of 2D motion picture footage of a rotating subject are recorded on holographic film. When viewed, the merged images are synthesized by the human brain as a 3-D image.
A holographic image can be seen by looking into an illuminated holographic and projecting the image onto a screen. The hologram captures light as it interests the whole area of the film. A photograph captures a small area of perspective, converting it into hologram expands the area of view with more clear depth of field. The physical medium of holographic film is light sensitive with a fine grain construction. Shared materials used are silver halide emulsions, dichromate gelatines and photo-polymers etc. Each have their own features and require different processing. Holograms can also be embossed including in security identification, such as on passports, credit cards, tickets and wrapping, as they are hard to copy without the original hologram.
On facing a hologram, what is most astonishing is that a surface seems to hold a space. The difference of scale between the visual shaping by the hologram structure and our material sense of it as a surface produces a perception of a virtual form, as if the light grasps its own shape.
Scope in future
- A holographic model of the universe might be able to explain nearly all spiritual and mystical experiences.
- The holographic model can explain synchronicity for ex- DNA, RNA and will revolute the biotech industry.
- Telepathy and even psychokinesis can be explained through the holographic model. Holography would be used to explain how our brains can store so many memories in so little space.
- Holography can take over our daily displays like mobile phones, LEDs etc. and will make more interactive and fun using them. The prediction of this scope is already started in visual world i.e. in movies and games.
Obstacles in the path of Hologram Technology
High production costs-it takes a lot of money and time to display professional holograms. We can take example of movies like Iron Man and their production costs.
Still developing technology- this technology is still under development, no full hologram is available till now, only we have created its visual copies to show them in movies like Iron Man etc.
Lack of studies on its impact in different areas of the human being-hologram requires human interaction and are produced of energy rays. There is no study till now of how much it can affect our body.
Material required –Graph Paper (To get precise measurements), Plastic Glass Sheet – Transparent (Main Gadget), Tape, Pen, Knife Glass Cutter, Smartphone Tablet
Cut the sheet precisely into 4 corresponding trapeziums and join them with a transparent tape to create a simple pyramidal frustum. Your setup is ready. Now, all the requirements are some hologram specific videos that one will easily get from the YouTube.
So, just place pyramidal frustum setup on smartphone display and let the physics do the rest as it makes 3-D hologram live.
Digital based imaging systems are merging in the holography workshop to produce visual displays that cannot be replicated by technology alone. Holographers are now able to use digital hardware and software tools along with laser based recording systems to create fully dimensional lively images that previously could not be produced in any practical way. Equally, computer graphic artists are using newly developed hologram printers as a unique output device for their work. This hybrid technology is resulting in further applications for lasers, computers, and visual-display technologies.
A software is the root of today’s holography technology. Holograms are designed in software’s only. Recently Apple patented the technology of 3D interactive holograms and may be they are working of new iPhone to make it capable of displaying holograms!
Holography may still be in its infant stage, but its potential applications are ambitious. Holographic Technology and Spectral Imagining has limitless applications, as far as the human mind can imagine. Holography being the closest display technology to our real environment may just be the right substitute when reality fails. With holography, educational institutions may become a worldwide village sooner that people thought, where information and expertise are within reach, knowledge sharing and mobility will only cost a second and learning will become more captivating and interactive. First, there is an urgent need to address the infrastructural lacks limiting the application of holography in education. More interestingly, the display medium of holography is very important. A 360 viewing angle is especially what is needed to maximize the use of holography in teaching. Being able to display a 3D hologram in free air is also vivacious, because interacting with holograms in an enclosed display may be clumsy. In order not to bind the use of holography to a non-interactive display medium, mixture with response technologies is compulsory. The haptic technology which makes it possible to touch and manipulate computer-generated object is especially important. As the arena of haptics continues to develop and integrates with holography, interaction with holograms becomes limitless. In future, holographic displays will be replacing all present displays in all dimensions, from small phone screen to large projectors and much more that we can’t even think right now.
