The race for faster and more furious just got big in the imaging and photography department. Japanese researchers have recently designed a motion picture camera which is capable of capturing 4.4 trillion frames per second. That’s right; it makes this snapper the fastest the world over. This technique that is known to be STAMP (sequentially timed all-optical mapping photography) is able to boast 450×450 pixels. The work by the Japanese researchers has been so popular that the Nature Photonics has published it.
Pump probe process is employed in the process for real time recording process. This is known to be the current high standard when it comes to high speed. It comprises pumping light at a particular subject before probing it for absorption. However, constructing an image would require the user to repeat the process and rerecord measurements. STAMP makes use of burst shot to capture images at a quick rate. You can imagine how efficient the optical shutter is by simply considering the fact that it captures multiple shots in one-trillionth of a second. It’s no surprise that STAMP is as much as 1,000 times quicker at capturing images compared to current line of cameras. Well done, University of Tokyo researchers.
The team of researchers demonstrated the high speed of the STAMP by capturing the conduction of heat. Just so that it’s out there, this constitutes transfer at a pace that is equal to a sixth of velocity of light. The study author is confident that it is a great new invention that will benefit people in a number of different fields. For instance, it could assist in understanding laser processing in semiconductor factories and the advance ultrasonic therapy in the field of medicine. The STAMP schematic shows an ultrashort laser being divided with the help of temporal mapping device into different ‘daughter’ pulses. These are then directed to various parts of an image sensor. All data that records with the help of the image sensor are used on a computer to create a movie.
