Holography is a technique that records an image in three dimensions, allowing the image to be viewed from different angles like a real object. It was invented in 1948 by Dennis Gabor, who wrote a foundational paper on the topic before lasers were even invented. A hologram is created through the interference of light waves from an object beam and a reference beam, which converts phase information into an amplitude pattern that can reconstruct the 3D image. Holography has many applications including entertainment, teaching and training through virtual reality, virtual communication, simulation and planning, and military and space technologies.

3. WHAT IS HOLOGRAPHY?
 Holography (from the Greek, whole + write) is the science of
producing holograms
 It is an advanced form of photography that allows an image to be
recorded in three dimensions.
 The technique of holography can also be used to optically store,
retrieve, and process information.

4. HOLOGRAPHIC PROPERTIES
 If you look at these holograms from different angles, you see objects from different perspectives,
just like you would if you were looking at a real object
 They usually just look like sparkly pictures or smears of color
 If you cut one in half, each half contains whole views of the entire holographic image

5. HISTORY
Dennis Gabor - Father of Holography and
Holographic Technologies
Dennis wrote a paper in 1948
that has become the foundation
of modern Holography.
The most interesting thing about all this is
that laser light had not even been invented
yet, when he wrote his paper

6. PRINCIPLE
Holography is a
two-step
process.
The second step
is the
reconstruction in
which the
hologram is
transformed into
the image.
First step is the
recording of
hologram where
the object is
transformed into
a photographic
record.

7.  A Hologram is the result of
interference occurring
between two waves,
 an object beam which is the
light scattered off the object
& a coherent background,
 the reference beam, which is
the light scattered off the
object & a coherent
background, the reference
beam ,
 which is the light reaching
the photographic plate

8. Photography vs. Holography
Conventional photography
Film sensitive
only to
intensity
distribution.
2-d dimension
of a 3-d scene
(object).
Photograph
lacks depth
perception.

9. Hologram:
 Converts phase information
into amplitude information (inphase - maximum amplitude,
out-of-phase – minimum
amplitude).
 Interfere wavefront of light
from object beam with a
reference wave.
 The hologram is a complex
interference pattern . It’s a kind
of diffraction grating.
If you tear a hologram in half, you can still see the whole image in each piece.The
same is true with smaller and smaller pieces.
