Recording video with normal cameras and long-wavelength terahertz radiation
  • The safe alternative to X-rays – long-wavelength terahertz radiation – is being used to create high-resolution images with conventional video cameras.
  • This radiation wasn’t used until now because it is very low-energy and no sensors picked it up, but researchers behind this study didn’t try to create a new sensor.
  • They came up with a way to convert terahertz photons into visible green photons, basically allowing a normal video camera to see it.
  • It’s too early to say whether this technology is viable for commercialization, but the team is working on improving it.
