A new camera has set an astonishing record, reaching a speed of 156 trillion frames per second. The revolutionary tool, developed by a team of researchers led by Professor Jinyang Liang from the Institut National de la Recherche Scientifique (INRS) in Quebec, will have impacts across many sectors.
Not only the field of scientific imaging, but also in medicine and computer science. The technology behind this exceptional camera uses an innovative optical technique to capture 132 frames from a single pulse of an ultra-fast laserallowing you to observe phenomena that occur in femtoseconds — a quadrillionth of a second.
This visualization capability opens up new perspectives for studying extremely fast processes, such as the absorption of photons by semiconductors o to demagnetization of alloy filmswith direct implications in the development of new magnetic computing memories and advanced ultrasonic medical treatments.
The device uses a special light source called “chirped laser”, a technology awarded the Nobel Prize for Physics in 2018, which extends the wavelengths of light so that different colors arrive at different times. This feature allows you to capture details of events at different times within a single laser pulse.
After capture, the data is processed through specialized software which, using a system similar to barcodes, distinguishes the various frames to create a short film lasting up to 850 femtoseconds. The innovation represented by this camera not only sets new standards in high-speed imaging but also offers an unprecedented window into phenomena that until now remained invisible to the human eye and traditional tools.
To help you understand the improvement, consider that just 2 years ago this camera was shooting at 10 trillion frames per second.
