History-of-Holography

1.

OPTICS · A SHORT HISTORY
History of
Holography
From a laboratory idea to images
that seem to float in space.

2.

THE PREMISE
More than a
photograph
Holography records a light wave, not only
brightness, but depth information.
A photograph records what light looked like. A hologram
preserves how the light arrived.

3.

1947
Dennis Gabor imagines holography while working on electron
microscopy.

4.

1960–1962
The laser makes the idea
practical.
Coherent light gives holography the precision and stability it needs.
Theodore Maiman builds the first working laser, 1960. Emmett Leith and Juris Upatnieks make the first laser holograms, 1962.

5.

TWO WAYS TO SEE LIGHT
Transmission or reflection
Both rebuild a three-dimensional view. They differ in how the light reaches the viewer.
Yuri Denisyuk · reflection, 1962 — Leith and Upatnieks · transmission, 1962
Transmission hologram
Reflection hologram
Light passes through to reveal the image.
Light bounces back toward the viewer.

1968
Rainbow
holograms
brighten the
view
Three-dimensional images become brighter
and easier to see.
Stephen Benton · Polaroid, 1968

7.

1971
Nobel Prize
and
recognition
Dennis Gabor receives the Nobel Prize in
Physics for inventing the holographic method.
Nobel Prize in Physics, 1971

1970S–1980S
Holography
leaves the lab
Holography moves into art, museums, security
features, and scientific measurement.

9.

THE FIELD OPENS
From image to instrument
Holography expands into science, art, measurement, and security.
Built on the work of Gabor, Denisyuk, Leith, Upatnieks, Benton, and Maiman
ART
SECURITY
See differently
Protect objects
SCIENCE
INSTRUMENT
Measure change
Read the unseen

10.

APPLICATIONS
Where holography helps
Security
Precision measurement
Microscopy

11.

NOW
Digital holography
Computers now calculate and reshape light in real time.
From Gabor's 1947 wave idea to software that computes it
The hologram becomes data: recorded, reconstructed, measured, and revised by software.

12.

THE IDEA
The idea
still feels
like magic
Record the wave. Rebuild the experience.
