The world of cameras is making strides to capture all of those things that even the human eye is not able to see it in its fullness, as you see waves of light travelling, and the decay of fluorescent molecules.
That is the promise of speed of the new camera, developed in the lab of Lihong Wang, professor of Medical Engineering and Electrical Engineering in the Department of Medical Engineering, Andrew and Peggy Cherng, who is able to take up to 70 trillion frames per second.
The work is published in the edition of April 29 in Nature Communications, where an article appears that describes the technology, entitled, “Imaging ultrafast single-shot that can reach 70 trillion frames per second“. The co-authors of Wang include Peng Wang, postdoctoral researcher in medical engineering, and Jinyang Liang, formerly of Caltech and now at the National Institute of Scientific Research in Quebec.
The camera technology, was baptized as a photography spectral ultra-fast compressed (CUSP). This allows you to combine a laser that emits pulses of extremely short light that only last a cuadrillonésima of a second (a femtosecond) with optical and a specialized type of camera. The lens splits the single pulses of femtosecond laser light in a train of pulses even shorter, with each one of these pulses capable of producing an image on the camera.
Professor Wang says the technology could open up new avenues of research in fields that include fundamental physics, the miniaturization of semiconductors of the next generation and the life sciences.
“We envision applications in a rich variety of phenomena, extremely fast, as the propagation of light ultrashort, wave propagation, nuclear fusion, photon transport in clouds, and biological tissues, and the decay of fluorescent biomolecules, among other things,” said the doctor behind this creation.
Caltech, where was this creation, is an institute of science and engineering of world-renowned. The Institute manages technology’s jet propulsion for NASA, sending probes to explore the planets of our solar system and to quantify the changes on our planet. Caltech also owns and operates research facilities on a large scale, such as the Seismological Laboratory and a global network of astronomical observatories, including Observatories, Palomar, and WM Keck.
