about holography- technology

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.

16. CONCLUSIO
N
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 BECAME A VERY
INTEGRAL PART OF HUMAN SOCIETIES AND
CIVILIZATIONS IN THE FUTURE
