Photonics: New approach to generating terahertz radiation will lead to new imaging and sensing applications Posted: 10 May 2012 06:56 AM PDT A new approach to generating terahertz radiation will lead to new imaging and sensing applications. The low energy of the radiation means that it can pass through materials that are otherwise opaque, opening up uses in imaging and sensing — for example, in new security scanners. In practice, however, applications have been difficult to implement.
