Svijetloscu svjetla protiv svijetlosti svjetla

Procitavsi vijest o novom nacinu komunikacije unutar suncevog sistema pomocu usmjerenih lasra i superosjetljivih detektora svijetla malko sam se prosuljao netom da vidim sta ima novoga u laserologiji, onak, bezveze. I otkrio sam neke vrlo interesantne vijesti.

Prva vijest kaze da ce se do kraja godine izvesti prvo testiranje laserskog oruzja. U.S. Airforce ce posloziti testni laserski top na Boeing 747 i vrlo vjerojatno spaliti neki cilj na zemlji.

Airborne laser weapon gets closer to takeoff
The flight will follow ground-based tests of solid-state lasers that are expected to end in August, Space.com reported this week. In the flight test, the low-power lasers will be fired at a target aircraft adorned with the painted image of a ballistic missile, according to a Boeing executive cited by Space.com.

A druga pak vijest opisuje posebno dizajniranu zraku nalik laseru koja kad obasja cvrsti predmet ucini taj predmet... nevidljivim tj. prozirnim. Za sada samo u infracrvenom spektru ali rade na tome da stvar profunkcionira i na vidljivom spektru. Nevidljivi objekti? Nevidljivi covjek?

Laser Makes Solids Transparent
A laser-like beam of light shined at a unique solid makes the material appear to disappear, according to a new study.
The effect, reported in a recent issue of Nature Materials, occurs at infrared light wavelengths, so it can't be seen with the human eye.

A nisu laseri tako losi ni kod nasih CD, DVD, HD DVD ili BD citaca i pisaca koji su dogurali do 50 GB po disku u dvostranim Blu-Ray diskovima. Ali... to je zastarjela tehnologija, glavna furka su holografski diskovi koji su dogurali do 300 GB po disku...

Holographic Firm Claims Data Storage Density Record
LONDON — InPhase Technologies Inc., a five-year old startup company trying to bring holographic data storage technology to market, has claimed to have recorded the highest data density of any commercial technology by recording 515 gigabits of data per square inch using its Tapestry system.

A kad smo vec kod svijetlosne komunikacije i podataka. Njemacko Japanska ekipa je postigla rekord u brzini prijenosa informacija prenjevsi podatke brzinom od 2,56 terabita u sekundi na udaljenosti od 160 kilometara. Kolicina podataka? Pa otprilike 60 DVD-a u sekundi. Skoro ko MAXadsl samo malo brze. :-))

New data transmission record - 60 DVDs per second
March 24, 2006 As the world’s internet traffic grows relentlessly, faster data transmission will logically become crucial. To enable telecommunications networks to cope with the phenomenal surge in data traffic as the internet population moves past a billion users, researchers are focusing on new systems to increase data transmission rates and it’s not surprising that the world data transmission record is continually under threat.

Ma strasna je ta svijetlost tj. ti laseri. Kazu da je jedina stvar brza od elektricne struje svijetlost pa je sasvim logicno da se superkompkuteri medjusobno sporazumijevaju... laserima preko optickih linkova, a ne preko spooorih bakrenih vodica. NEC je napravio komunikacijske chipove koji pretvaraju struju u laserske impulse i ubrzao jedan jadni mali kompukter u rangu petaflopa (omg di je to oslo).

NEC Laser Chips to Speed Up Supercomputers
To provide some more detail, Knight explains that these communications chips convert electronic signals into light which will travel over optical fibers between two of these chips to reduce any latency on an all copper connection.

A dok ne proradi onaj americki laserski top u Boeingu 747, Lord Ingénierie se pobrinuo da se makar mozemo zabavljati sa upucavanjem,tocnije rastjerivanjem vrabaca i napravio TOM500, zeleni laser koji ce rastjerivati nocne ptice po zracnim lukama diljem svijeta- Heh, zeleni laser, kazu da ga ptice totalno ne smekaju i bjeze. A ajd, kad to ornitolozi kazui valjda je istina, ja cu si morati nabaviti jedan da mi rastjeruje dosadne golubove (letece stakore) ispred prozora jer mi stvarno pocinju ici na zivce sa gugutanjem.

Green laser beams could beat deadly bird threat at airports
Laser beams sweeping airport runways to scare away birds could help civil aviation authorities in the Middle East beat a big threat to aircraft safety
