A camera was developed in the USA that can shoot 70 trillion frames per
second. The new technology is to be used primarily in biochemistry and in
basic physics.
Pasadena (USA). If you were to be photographed and blinked by the new camera
, the camera would take over a trillion pictures in this incredibly short
moment. This example illustrates very well how fast the camera developed at
the California Institute of Technology (Caltech) really is.
Lihong Wang, professor of electrical and medical technology, and his team
have developed an ultra-fast camera that can take up to 70 trillion images
per second. This is so fast that it can even record light waves as they
travel or molecules decay.
Laser pulses for one femtosecond
Wang describes the technology he and his team developed behind the camera as
compressed ultra-fast spectral photography (CUSP). In the detailed
description in the journal Nature Communications you can quickly see that
the new camera is in many ways similar to older cameras developed by him.
This includes, for example, a phase-sensitive device for compressed
ultra-fast photography (pCUP), which can take a trillion pictures per second
of transparent objects.
In the new CUSP process, a laser that emits ultrashort light pulses with a
duration of only one billionth of a second (one femtosecond) is combined
with an optical system and a very special type of camera. The optics break
down the ultrashort laser pulses into even shorter pulses, whereby each of
these even shorter pulses can generate an image in the camera.
Camera is to be used in biochemistry and basic physics:
According to his own statements, Wang can imagine using the new ultra-fast
camera in areas such as basic physics, which he would like to miniaturize in
the life sciences. "We envision applications in a variety of extremely fast
phenomena, such as ultra-short light propagation, wave propagation, nuclear
fusion, photon transport in clouds and biological tissues, and fluorescent
decay of biomolecules," added Wang.
