Scientists From University Of California Have Maded The Superfast Camera

May 6th, 2009

Physicists from University of the State of California have created the fastest for today the digital camera: she is capable to shoot one scene of video each 163 nanoseconds. Thus, for a second the new device removes 6,1 million frames. On it informs Nature News, and article of contributors is published in log Nature. By word physicists, speed of operation of their device almost six times above, than for best of existing clones.

Principle of operation of the camera the following. At first the object irradiate with impulses of infra-red radiation. Thus lighting is formed in such a manner that various parts of the studied object appear are shined by radiation with a various wavelength. The ambient light is skipped through a special fiber optic cable which possesses that property that electromagnetic waves of different length move in it with different speed: “long” waves moves faster “short”.

By word the contributors, the new technology possesses several advantages in comparison with already existing. So, for example, one detector (in the usual digital camera it is necessary to parse electrical signals from the whole two-dimensional array of detectors) participates in camera operation only. For this reason, scientists mark, they manage to achieve so a shooting high speed. Besides contributors do not use expensive materials in the installation: the majority of details is available on free sale.

Weakness of new technology is while that the scientist was possible to receive the map, in which only 2500 pixels. By word the contributors, it is possible to overcome the given difficulty, using more expensive materials in camera manufacture.

Other group of researchers of university Rajsa used a permanganate combination of cale and sulfuric acid to cause dot destruction of walls nanonotebook. After that tubes “were unbuttoned” in strips.

The analysis of the second group of researchers has allowed to establish that received nanotubes were much wider (nearby 100-500 nm) than what turned out the first method. The given objects any more did not possess semiconducting properties. The given method allows to receive quality strips in enough considerable quantities. According to researchers, it can potentially find application by manufacture of electronics, solar batteries, and also at creation of composit materials.
