3. HOLOGRAPHY
• Holography is a photographic technique that records
the light scattered from an object, then presents it in a
three-dimensional way.
• It is an advanced form of photography that allows an
image to be recorded in the three-dimension
• The technique of holography can also be used to
optically store, and retrieve three-dimension
information

4. THREE-DIMENSIONAL HOLOGRAPHIC
PROJECTION TECHNOLOGY
• 3-D holographic projection
technology is loosely based on
an illusionary technique called
Peppers Ghost.
• First used in Victorian theatres
across London in the 1860s.

5. HOLOGRAM - HISTORY
• Hungarian-British physicist Dennis Gabor invented
the hologram in 1947.
• He was awarded the Nobel Prize in Physics in 1971
"for his invention and development of the
holographic method".

6. TYPES OF HOLOGRAPHY
• Reflection Hologram: Created by reflecting laser light off an object and viewed by
shining a laser beam on it from the same angle as the original beam.
• Transmission Hologram: Created by passing laser light through an object onto a
photographic plate, viewed by shining a laser beam through it from the same angle
as the original beam.
• Computer-Generated Hologram (CGH): Created using digital devices to simulate an
object's interference pattern, the resulting hologram can be printed or displayed on
a screen, used in applications such as 3D displays.

7. WORKING OF HOLOGRAM
The time-varying light field of a scene with all its physical properties is to be recorded
and then regenerated. Hence the working of holography is divided into two phases:
• Recording of a hologram.
• Reconstruction of a hologram.

13. A DOUBLE PARABOLIC MIRROR PROJECTION SYSTEM
• The double parabolic projection system is composed of double parabolic mirrors.
• The full-color computer-generated hologram is a real image, which could be remade
a virtual image through the double parabolic projection system.
• The image magnification appears to be 1.2 times the original.
• The horizontal viewing angle appears 360° and the vertical viewing angle 15-75°.

20. CONCLUSION
In conclusion, holograms are a fascinating technology with many different
types, including reflection, transmission, and computer-generated holograms. These
holograms are used in various applications, such as art, security, advertising, and 3D
displays. With ongoing advancements in technology, the potential uses for holograms
continue to expand, offering exciting possibilities for the future.
