With Viking's recent post on intercepting an ET signal, I wanted to re-examine a hypothesis that the ET's (some at least) are using visible light to communicate. This is so exciting because no researcher has discussed the phenomenon that I'm aware of. Also, it's an amazing opportunity for our collective minds to examine the possiblities we might uncover. Ultimately I hope to decode the strange intricate light display recorded from last year. In the past post the feeling was that there was a huge amount of information that can be traveling on the light waves. Without knowing the translation it seems impossible. I agree somewhat until I watched the video below and was surprised. Anyway I think a proper place to start would be a definition and a small background story...
I hope the thread is interesting enough that we might explore it together..:)

Free-space optical communication (FSO) is an optical communication technology that uses light propagating in free space to transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar. This contrasts with using solids such as optical fiber cable or an optical transmission line. The technology is useful where the physical connections are impractical due to high costs or other considerations.
In 1880 Alexander Graham Bell and his assistant Charles Sumner Tainter created the Photophone, at Bell's newly established Volta Laboratory in Washington, DC. Bell considered it his most important invention. The device allowed for the transmission of sound on a beam of light. On June 3, 1880, Bell conducted the world's first wireless telephone transmission between two buildings, some 213 meters apart. Its first practical use came in military communication systems many decades later. Carl Zeiss Jena developed the Lichtsprechgerät 80 (direct translation: light speaking device) that the German army used in their World War II anti-aircraft defense units.
The invention of lasers in the 1960s revolutionized free space optics. Military organizations were particularly interested and boosted their development. However the technology lost market momentum when the installation of optical fiber networks for civilian uses was at its peak. Many simple and inexpensive consumer remote controls use low-speed commnication using infrared (IR) light. This known as consumer IR technologies.
Free Space Optics are additionally used for communications between spacecraft.
In outer space, the communication range of free-space optical communication is currently in the order of several thousand kilometers, but has the potential to bridge interplanetary distances of millions of kilometers, using optical telescopes as beam expanders. The distance records for optical communications involved detection and emission of laser light by space probes. A two-way distance record for communication was set by the Mercury laser altimeter instrument aboard the MESSENGER spacecraft. This infrared diode neodymium laser, designed as a laser altimeter for a Mercury orbit mission, was able to communicate across a distance of 15 million miles (24 million km), as the craft neared Earth on a fly-by in May, 2005. The previous record had been set with a one-way detection of laser light from Earth, by the Galileo probe, as two ground-based lasers were seen from 6 million km by the out-bound probe, in 1992.

Using the visible light spectrum of LEDs offers a more energy-efficient source of light and is a viable alternative to an overburdened radio bandwidth system. There are many data-hungry applications, and the radio spectrum is limited. The use of wireless mobile applications is growing, and we are running out of radio spectrum to use. We had a few ideas and weren’t sure if they would work, but we worked on the release of radio-frequencies spectrum to provide more wireless capabilities for the future.
The visible light spectrum is 10,000 times larger than the radio- frequencies spectrum, so I wanted to uncover other possible technologies.
Li-Fi is the term they coined to describe how their concept works. The light intensity of LEDs can be controlled very rapidly and is faster than the human eye can detect.
By a small device in the light fitting, digital information can easily be converted into minute variations in light, even at very low levels of light, and transfer to other devices many times faster than the data coming into the building.
The light emissions are harmless to humans and can be transmitted even if the light source is dimmed or reflected around the room.

There does seem to be research in this field and I can only imagine how far we are in this area that we dont know.
The video shows an simple example of the possiblities.

Here is one of the clips that made me suspect there was more than a display for the camera going on.

Maybe an experiment can be developed using LED's? Or perhaps someone knows Brad Meltzer of Decoded? ...:) A shame there might be evidence of ET communication sitting in the archive and I should at least make light of it...
