Scientists have developed a camera capable of capturing 156 trillion frames per second Posting in CHAT: Russia The team has developed a camera capable of capturing images at a frequency of 156.3 terahertz, which is equivalent to 156.3 trillion frames per second. The more frames per second the camera captures, the more detail the viewer will be able to see. What if the number of frames per second reaches hundreds of trillions? How slow can slow motion be? A team of scientists decided to answer this question by developing a new scientific camera called SCARF, which stands for swinging aperture real-time femtophotography. The entire development process of this camera is described in detail in a new study published in the prestigious scientific journal Nature. Study leader Professor Jingyan Liang of the National Institute of Research Canada (INRS), known for his achievements in ultra-fast cameras, explained that traditional time-lapse techniques have their limitations. “For example, phenomena such as optical chaos, shock wave interaction with living cells, and femtosecond laser ablation cannot be studied using traditional methods,” Liang said. To overcome these limitations, Liang's team developed a new camera that uses image processing techniques to capture spatial information. The camera achieves this by allowing light to enter the sensor with a slight delay, allowing it to shoot at 156.3 trillion frames per second. The data captured by the camera is then fed into a computer decoding algorithm that accurately identifies each of the time-spaced inputs and then converts them into complete images. As INRS public relations representative Julie Robert explained, the imaging technology used allows for extremely high-quality images to be taken. Fast scanning of the static coded aperture without the distortion of the fast motion phenomenon. This enables incredible sequential frame encoding speeds of up to 156 Terahertz for every single pixel in a CCD camera. Such outstanding results can be achieved with a single shot, with the ability to adjust both the frame rate and spatial zoom in reflection and transmission modes. It is worth noting the interesting fact that the research team was able to develop the SCARF camera using only widely available ones. passive optical elements. The creators themselves characterize this ultra-fast camera as an economical, energy-efficient and at the same time high-quality solution for high-precision measurements. Source link Source link
