2. HOLOGRAM
• To understand how a holographic projector works we
need to know what a hologram is.
• Holography is a photographic technique that records
the light scattered from an object, and then presents it
in a way that appears three-dimensional.

3. 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".
• Originally, used in electron microscopy, where it is
known as electron holography

4. CATEGORIES OF HOLOGRAPHY
In recent years, the development of holography gradually toward to
digital holography .
• HOLOGRAPHY.
• DIGITAL HOLOGRAPHY.
• COMPUTER GENERATED HOLOGRAPHY.

5. DIGITAL HOLOGRAPHY
FIGURE 1
• Digital off-axis holography uses a CCD array to record
a digital hologram where the reference beam interferes
with the object beam.
• The data are transmitted to a computer and analyzed.
FIGURE 2
• A digital hologram is recorded on a CCD array,
and the data are processed on a computer to
create a digital 3D model in the computer.
• That model is then displayed on the screen,
shown as if in three dimensions.

12. CONCLUSION
3D holographic projection is a rapidly growing technology that will change how we
view things in the new era. It will have tremendous effects on all fields of life.
Holographic Technology and Spectral Imagining have endless applications, as far as
the human mind can imagine.
