Laser and Holography and their Uses

Laser and Holography and their Uses
Why write about holography in a book of conspiracy?
It can be used to create events apparent which are not real life events.
Whats the caveat?
It can be used by secret service to invent an event such as 9/11 scenario. I won’t write anything more but top brace in the Bush Administration was privy to this holographic creation.
What if aliens who fear the man of attack would do?
They are with superior technique would create alien presence using a probe that is manipulated from a mother ship out of human vision.
There is no danger to their life.
If we assume Roswell incident did happen and aliens were captured and used as hostages, that is the most likely scenario that would have evolved.
Let us imagine they could mount an operation to stage something like Phoenix Lights.
Necessary ground work to make humans start believing in alien or extraterrestrial beings (EB) is made in holographic form and choreographed. That is the level they would go for their own safety and read message of “no ill will” to humans.
Equally if Vatican or a peudo-scientist gets hold of this technology they will certainly mount an operation for “the god has come back from heaven”, live.
That is a likely scenario!
In a few years time we will have holographic studios and “Television” at home.
The technology is developing fast.
Below is an introduction to how holography works.
Holography dates from 1947, when British (native of Hungary) scientist Dennis Gabor developed the theory of holography while working to improve the resolution of an electron microscope.
Gabor coined the term hologram from the Greek words holos, meaning "whole," and gramma, meaning "message". Further development in the field was stymied during the next decade because light sources available at the time were not truly "coherent" (monochromatic or one-color, from a single point, and of a single wavelength).
This barrier was overcome in 1960 by Russian scientists N. Bassov and A. Prokhorov and American scientist Charles Towns with the invention of the laser, whose pure, intense light was ideal for making holograms.
In that year the pulsed-ruby laser was developed by Dr. T.H. Maimam. This laser system Leith(unlike the continuous wave laser normally used in holography) emits a very powerful burst of light that lasts only a few nanoseconds (a billionth of a second).
It effectively freezes movement and makes it possible to produce holograms of high-speed events, such as a bullet in flight, and of living subjects.
The first hologram of a person was made in 1967, paving the way for a specialized application of holography: pulsed holographic portraiture.
In 1962 Emmett Leith and Juris Upatnieks of the University of Michigan recognized from their work in side-reading radar that holography could be used as a 3-D visual medium. In 1962 they read Gabor's paper and "simply out of curiosity" decided to duplicate Gabor's technique using the laser and an "off-axis" technique borrowed from their work in the development of side-reading radar. The result was the first laser transmission Upatniekshologram of 3-D objects (a toy train and bird). These transmission holograms produced images with clarity and realistic depth but required laser light to view the holographic image.
Their pioneering work led to standardization of the equipment used to make holograms. Today, thousands of laboratories and studios possess the necessary equipment: a continuous wave laser, optical devices (lens, mirrors and beam splitters) for directing laser light, a film holder and an isolation table on which exposures are made. Stability is absolutely essential because movement as small as a quarter wave- length of light during exposures of a few minutes or even seconds can completely spoil a hologram. The basic off-axis technique that Leith and Upatnieks developed is still the staple of holographic methodology.
DenisyukAlso in 1962 Dr. Yuri N. Denisyuk from Russia combined holography with 1908 Nobel Laureate Gabriel Lippmann's work in natural color photography. Denisyuk's approach produced a white-light reflection hologram which, for the first time, could be viewed in light from an ordinary incandescent light bulb.
Another major advance in display holography occurred in 1968 when Dr. Stephen A. Benton invented white-light transmission holography while researching holographic television at Polaroid Research Laboratories. This type of hologram can be viewed in ordinary white light creating a "rainbow" image from the seven colors which make up white light. The depth and brilliance of the image and its rainbow spectrum soon attracted artists who adapted this technique to their work and brought holography further into public awareness.
Benton's invention is particularly significant because it made possible mass production of holograms using an embossing technique. These holograms are "printed" by stamping the interference pattern onto plastic. The resulting hologram can be duplicated millions of times Bentonfor a few cents apiece. 

Consequently, embossed holograms are now being used by the publishing, advertising, and banking industries.
