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.
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
HISTORY
Dennis Gabor - Father of Holography and Holographic Technologies Dennis wrote a paper in 1948
that has become the foundationof modern Holography.
The most interesting thing about all this is that laser light had not even been invented
yet, when he wrote his paper
PRINCIPLE
Holography is a two-step process.
First step is the recording of hologram where the object is
transformed into a
photographic record.
The second step is the
reconstruction in which the hologram is transformed
into the image.
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 directly.
Photography vs. Holography
2-d dimension of a 3-d scene
(object).
Photograph lacks depth perception.
Film sensitive only to
intensity distribution.
Conventional photography
Photography vs. Holography
Hologram:
Converts phase information into amplitude information (in-phase - 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.
