Authors of a new study have presented to the world the fastest camera ever. The latter can be used to capture high-resolution images of processes that occur at incredibly high speed, like the conduction of heat. The images are then synchronised into a movie that illustrates occurrences that were until now mysteries to us because of their fast evolution. The work was published in the journal Nature Photonics.
Brace yourselves, everyone, the world’s fastest camera has seen the light of the day in the land of the rising sun! Japan is well-known for its ingenuity and brilliance of coming up with exciting inventions. It has not disappointed this time either. Japanese researchers have created a motion picture camera able to take 4.4 trillion frames per second, producing images of resolution 450 x 450 pixels. The camera will prove to be specially useful for high-speed photography which has been defined as the art of taking pictures of fast-evolving processes. The earliest application of high-speed photography involved shooting horse gallops and the study of supersonic flying bullets. Other fields that need high-speed photography includes photochemistry and plasma physics.
The technique employed has been named “sequentially timed all-optical mapping photography” (STAMP). STAMP is superior to the current technique used, known as pump-probe process, which entails repetitive measurements in order to build up an image – STAMP is thus not limited to this: it is so much faster. It can use single-shot bursts to get the images. it can capture images consecutively in a short lapse of time: less than one-trillionth of a second. The newly invented camera is thus around 1000 times faster than the standard high-speed cameras.
When the camera was put to use by the scientists, they captured the dynamic process of heat conduction – the latter occurs at a speed which is around one-sixth of the speed of light. The data captured by the image sensor are then fed into a computer which caters for the digital processing of the information into a movie.
The invention is deemed to be highly promising. It will take research in many fields of work to a wholly new level. For instance, researchers will now be better equipped to study deeper laser processing and ultrasonic therapy.
The world just go cooler!
