Recently, a research team at the Lund University has introduced the fastest high-speed camera designed until now that can record the correspondent of an astounding 5 trillion frames each second, rapid enough to picture the motion of light. This novel super-fast film camera will hence enable capturing of unbelievably speedy processes in physics, chemistry, biomedicine, and biology, until now which was not captured on film.
To demonstrate this new technique, the team has effectively captured how light travels a distance equivalent to the paper’s thickness. In fact, it only requires picoseconds, but the process on the film has been decelerated by a trillion times. At present, images are captured one by one in a series by the high-speed cameras; however, the new technique is founded on a novel algorithm. It captures several coded pictures in one image and later resolves them into a video sequence.
In other words, the process consists of revealing the object to the light in the form of laser flashes and each of the light pulse is provided with a unique code. The entity reflects the flashes of light that unite into one photograph. They are consequently separated with the use of encryption key. Initially, the film camera was proposed to be utilized by researchers who actually want to get enhanced insight into several of the tremendously fast processes that take place in nature. Numerous of them occur at a femtosecond and picosecond scale, which is incredibly rapid.
For the team itself, achieving a new speed record is not the biggest advantage of this method but that it will enable them to capture hoe certain substances alter in the same process. The team spent most of the time on studying combustion. Combustion is regulated by several ultrafast processes at the molecular level that can now be recorded on film.
The team intends to use this camera for studying the plasma discharges chemistry, the lifetime of quantum states in biological tissue and in combustion environments, as well as how chemical reactions are commenced.
It is an amazingly unbelievable speed. What do you think about it?
