3. 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

6. How
holograms
work
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
•Reconstruction

7. 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

9. 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.
