Using smartphones, you can record videos at a speed of about 1000 frames per second. Professional cameras capture motion at up to 10,000 frames per second.
Researchers at the California Institute of Technology have been able to develop technology that can record 70 trillion frames per second. This way, you can even see the movement of a wave of light.
In 2014, Dr. Becker led the presentation of the original CUP (Compressed Super-Speed Photography) technology, which can take 100 billion images per second.
By 2018, the technology had been improved and was called T-CUP, and the recording speed reached 10 trillion frames per second.
The new CUSP (Compressed Super Fast Spectrum Photography) technology increased the recording speed seven times to 70 trillion frames per second.
The core of the superfast CUSP is a pulsed laser that emits ultra-short light pulses of one femtosecond (10-15 s). The optical system separates these pulses into even shorter flashes. These fractional pulses illuminate the subject and then pass through another optical system to the image sensor, which produces the final image.
