Terahertz radiation is the range of radiation between the infrared and radio spectrum, the wavelength of which
Tracking terahertz radiation will make it possible to observe the vibrations of electrons in solids and the vibrations of crystal lattices, and will also allow you toX-ray objects for the presence of prohibited substances.
Now scientists for the first time have found a way to track changes in terahertz radiation in slow motion or rapid shooting. To do this, they passed the signal through a cloud of excited cesium atoms.
When interacting with atoms, terahertz radiation is converted into a green stream in the visible range, which can be monitored at a frequency of a thousand frames per second.
Earlier, engineers from MIT developed a technological process that can form the basis for creating flexible electronics - “remote epitaxy”.
