Holographic projection technology is the new sign of future technology and communications. The 3D
holographic projection technology is also known as "Musion Eyeliner."Holography is a technique that is used to
display objects or scenes in three dimensions. These 3D images are called holograms.
TYPES OF HOLOGRAMS: 1.Reflection Hologram 2.Transmission Holograms 3.Computer Generated Holograms.
The holographic projection is a kind of 3D technology of withoutwearing anyglasses, and viewers can see the
three-dimensional virtual character. The importance of this technology and how it represents the new wave in
the future of technology and communications, the differentiate application of the technology, the fields of life
it will dramatically affect including business, education, telecommunication and healthcare.
The paper also discusses the future of holographic technology and how it will prevail in the coming years
highlighting how it will also affect and reshape many other fields of life, technologies and businesses.
We can often see the three-dimensional holographic communication technology in science fiction movies,
using the principle of three-dimensional computer graphics, and the distant person or thing can been projected
in the air in the form of th ttree-dimension.
ABSTRACT
4. INTRODUCTION
Holography, often known as hologram technology, is a type of photography
that records the light emitted by an object and then projects it as a three-
dimensional (3D) object that can be seen without the use of any extra
equipment.
It can often see the three-dimensional holographic communication
technology in science fiction movies, using the principle of three-dimensional
computer graphics, and the distant person or thing can been projected in the
air in the form of three- dimensional.
5. HOLOGRA
M
It is an advanced form of photography
that allows an image to be recorded in
three dimensions.
"Holography is a method of producing
a visual three-dimensional (3-D) image
of an object by means of light wave
patterns recorded on a photographic
plate."
6. • Holography is a technique that allows the light scattered from an object
to be recorded and later reconstructed.
• The technique to optically store, retrieve, and process information.
• Preserve the 3-D information of a holographed subject
7. 1.Laser Red: Users, usually helium-neon (HeNe) lasers, are common in
holography. These are coherent light source.
2.Beam Splitter: This is a device that uses mirrors and prisms to split
laser beam of light into two beams.
Object beam (directed onto the object) and
Reference beam (travels directly onto the recording medium)
REQUIREMENTS OF
HOLOGRAPHY
8. 3.Mirrors: These direct the beams of light to the correct locations
4.Holographic film: Holographic film can record light at a very high
resolution, which is necessary for creating a hologram. It's a layer of
light- sensitive compounds on a transparent surface, like
photographic film.
9. • Laser light-usually helium-neon (HeNe) laser is used.
• Beam splitter-device that use mirrors and prisms to split laser beam into two
beams:
• 1. Object beam 2. Reference beam
• Mirrors-Direct the beams of light to correct locations
• Holographic Film-to record image very high resolution
• Can be seen through naked eye
• Image floats in free space
WORKING OF
HOLOGRAPHY
• Working of holography is divided into two
phases:
• Recording
• By replacing the conventional holographic plate with a digital camera and an
optoelectronic 2D screen, we can capture and display holographic video.

12. ADVANTAGES
1.Cost effective
2.Higher storage capacity
3.Increased feasibility of objects(depth)
5.Ability to combine with other
technologies
6.Enables the achievement of multiple images
on a single plate including 3D images.
8.t does not require special glasses to view
and can be viewed from any angle.
9.t does not require any projection screen.
13. DISADVANTAGES
1.It is not easily seen in the presence of fluorescent lighting.
2.Use of applying the concept of holographic projection in
the design of products are costly.
3.It is time consuming to construct images using 3D
holograms.
4.Holographic data storage suffers from noise and
sensitivity issues. Moreover it has material limitations.
14. APPLICATIONS
• Also applied in weather forecasting, virtual reality, digital art, and
security.
• Health Care: A doctor needed to get a close look at someone's arm, they could use the
3D image of the arm as seen by a camera to get a detailed.
• Credit Card: It represents a valid card and is a sign that the card is legal.
• Education: Holograms are an innovative technology it can help students visualize
abstract concepts, better understand complex subjects, engage more with their
learning, communicate more effectively with their teachers.
• Advertising: Brands use holographic display advertising to exhibit their products in a
3D view through LED light shows.
• Engineering: Holography is also used to detect stress in materials. ..
• Militaryfield operator can quickly see if he can communicate with another person or
asset.
15. FUTURE
SCOPE
• Holograms could soon become the next
wave of communications, connecting
people with spatially-designed virtual
objects to add depth, realism, and
emotional impact to face-to-face
communications.
• In future all displays like televisions,
mobile phone displays, projector
displays will be replaced by
holographic displays
16. • Holographic Technology has endless applications as far as the
human mind can imagine. Holographic Technologies are not just
about art or business communication, they are about safety,
security, education, planning and the strength of our civilization
here and beyond. Holographic Technology will become a very
integral part of human societies and civilizatioin the future. This
technology has recently been created to bring live holograms from
one location and beam them into any location in the world.
