What is holography
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

Why
holographic display
A high resolution three
dimensional recording of an
object
Glasses free 3D displayeed for

How
holograms
workThe 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
•Reconstruction

Recording
of hologram Basic tools required to
make a hologram
includes a red lasers,
lenses, beam splitter,
mirrors and holographic
film
Holograms are recorded
in darker environment

Recording a hologram 8

Process
When the two laser beams reach the recording
medium, their light waves intersect and interfere with
each other. It is this interference pattern that is
imprinted on the recording medium.

Conclusion Holographic Technology
and Spectral Imagining has
endless applications, as far
as the human mind can
imagine
In future, holographic
displays will be replacing
all present displays in all
sizes, from small phone
screen to large projectors
