Holography is divided into two processes which are recording and reproduction,the interference fringes is generated
on the
holographic plate through the superposition
between the reference light and the reflected light during the recording. Then, after the
holographic plate is processed in the darkroom, an image exactly same to the original object will be reproduced from the interference
pattern on the photosensitive sheet by
diffraction. Compared with ordinary photographic, Holography not only records the
amplitude
of light field of the object, but also records the relative phase of the reflected light waves. Holography is widely used in holographic
microscopy, holographic security,
data storage, deformation
measurement, holographic interferometry and etc.
Three-dimensional color holograms can
reflect the original information of
objects more accurately than
monochromatic holograms, so they have a
broad application prospect in
holographic display. In order to realize
high-definition, large-format and
THREE-DIMENSIONAL color holographic
display, holographic Angle multiplexing,
holographic rotation multiplexing and
holographic wavelength multiplexing are
used to realize multi-multiplexing
holographic display in liquid crystal
thin film, and RGB tri-color laser is
used to realize the reproduction of RGB
image components. The RGB image
components are recorded in three
different holograms, which are recorded
at the same recording point of the
liquid crystal film using angular
multiplexing. The green laser is used as
a recording light to record three
holograms at the same time, and then the
red, green and blue laser reads the
corresponding holograms respectively.
These three RGB images are combined into
three-dimensional color holograms.
At present,
three-dimensional color holographic
technology in three-dimensional film,
television, exhibition, microscopy,
interferometry, projection lithography
and surveillance, underwater detection,
metal interior detection, preservation
of precious historical relics, works of
art, information storage, remote
sensing, The study and recording of
transient phenomena, transient processes
(such as explosions and combustion) with
extremely rapid changes in physical
states have been widely used.
