Almost everyone has experienced the problem of being blindfolded at least once in the photo. However, a new camera system developed by the California Institute of Technology (Caltech) can shoot 70 trillion frames in the blink of an eye.
Most phone cameras on the market can record slow motion images under 1,000 frames per second. Commercial equipment can usually shoot a few thousand frames. However, researchers have uncovered the world’s fastest camera system that can shoot up to 70 trillion frames per second thanks to a new technology they have developed.
The technology developed in Caltech was called compressed ultra-fast spectral photography (CUSP). The system, which can reach incredible frame rates, does not work like an ordinary camera. The technology uses extremely short laser light pulses, each of which takes only one femtosecond. This time even captures light waves in motion, quadrillion seconds.
CUSP technology increased the frame rate of the camera system 7 times
The developed optical system separates laser pulses into shorter flashes. Each of these strokes then hits a special sensor on the camera, producing an image, which takes place 70 trillion times per second.
The CUSP system is based on an older technology developed by the lead author of the study, Lihong Wang. The first system, known as compressed ultra-speed photography (CUP), reached its top speed in 2014 at 100 billion frames per second. Wang and his team managed to capture 10 trillion frames per second using an advanced version of technology called T-CUP in 2018.
Now making the technology 7 times faster, researchers believe that CUSP technology can be used to research the ultra-fast world of basic physics and help develop smaller, more sensitive electronic devices. “We envision applications in a variety of very fast phenomena, such as ultra-short light emission, wave propagation, nuclear fusion, photon transport in clouds and biological tissues,” says Wang. Experts around the world use different methods to increase the frame rate. Japanese researchers reached 4.4 trillion frames per second in 2014, and a team in Sweden exceeded 5 trillion in 2017.
