Imagine that on a beautiful day when the coronavirus comes out of our lives, you are getting together with your friends and having fun at a time that you have not had in the past few months. You wanted to crown this time by taking a selfie to upload to Instagram. But what is that? Although he presses the shutter button quite fast, his eyes are closed. Also, this is not the first time you have a problem. As if Murphy’s Law is working, you see your eyes closed every time you take a selfie. Fortunately, we have at least as good news as your heart. The California Institute of Technology (Caltech) appears to have found a solution to this problem.
THE FASTEST CAMERA IN THE AMAZING WORLD
The California Institute of Technology has developed a new camera system. Called Compressed Ultrafast Spectral Photography (CUSP), the new camera system takes 70 trillion frames until it blinks. Therefore, CUSP is the fastest camera system in the world, as well as phones that can shoot up to a thousand frames. So how can CUSP take billions of photos at the same time?
IN THE LIGHT OF THE SECRET LASER OF THE WORK
The answer is quite simple. First of all, CUSP does not have technology like normal cameras. Its technology is quite different from the other cameras we use. The secret lies in the pulses of laser light, each of which lasts only a femtosecond. The optical system in CUSP separates these pulses of laser light into shorter flashes and drops them into a special sensor. An image is formed on this sensor. In every second, the system does this 70 billion times. Think about it, CUSP gets 70 billion frames in the blink of an eye.
CUSP ARRIVES TODAY FROM 2014
CUSP is not really a new technology. Lihong Wang, who is leading this study, took the fruits of his work for the first time in 2014 and managed to reach CUSP at 100 billion squares per second. As a result of the improvements made until 2018, this number has reached up to 10 trillion squares. By 2020, the pronounced number is 70 trillion squares.
WILL PROVIDE GREAT BENEFITS
CUSP researchers believe that the system will be of great benefit to the development of smaller and more sensitive electronic devices. Lihong Wang says they foresee applications in various very fast phenomena, such as ultrashort light emission, wave propagation, nuclear fusion, transport of photons in clouds and biological tissues. So thanks to this technology it seems that smartphones can also make quite small structures more useful. So the days when our eyes are not closed may be very close.
