Description: Introduction to holography:- Holography is proposed by D.Gabor in 1948, it initially aimed at solving the resolution problem of electron microscope with coaxial holography (Inline Hologram) . Because of the invention of the coherent light source (laser) (1964), holography was able to be realized. The difficulties of holography 1.The photosensitive material formulations, 2.The diffraction efficiency is vulnerable to decay after a long time.

In recent years, the development of holography gradually toward to digital holography and computer generated holography.

Introduction to holography
Holography

is proposed by D.Gabor in 1948, it
initially aimed at solving the resolution problem of
electron microscope with coaxial holography (Inline Hologram) . Because the invention of coherent
light source (laser) (1964), holography was able to
be realized.

Full-color computer-generated hologram (I)
A Double Parabolic Mirror Projection System
The double parabolic projection system is composed of double parabolic
mirrors. The full-color computer-generated hologram is a real image, which could
be remade a virtual image through the double parabolic projection system. The
image magnification appears 1.2. The horizontal viewing angle appears 360° and the
vertical viewing angle 15-75°.

Full-color computer-generated hologram (II)
Pyramid-type floating projection system





Four image display surfaces could be used for presenting distinct
information and switch the angle of view for the 360 degree viewing.
The 3D perception of dynamic floating images could be reinforced by the
pyramid structure.
The matching of algorithms and optical mechanisms we developed could
present various colors on different display surfaces.

I) Single LCoS
Warsaw University of Technology, M. Makowski et al.
In 2010, M. Makowski et al.used a single SLM to keep the setup very simple. Division
of the SLM area into three sections addressed by three Fourier holograms calculated for
red, blue, and green color components

KAIST, J. Hahn et al
In 2014, J. Hahn et al.used RGB LED as light source, and realized the
non-intrusive CGH HMD. But it only display in single color.
