Terahertz technology illuminates microscopic and quantum worlds.

Scientists at Loughborough University have demonstrated that a terahertz wave camera can capture 3D images of microscopic items hidden inside small objects. The team's latest study could have major implications for a range of fields with relevance in cancer screenings, security, and materials research. Terahertz waves are a vastly unexplored part of the electromagnetic spectrum with frequencies ranging between microwave and infrared light. They have several properties that make them extremely useful, such as their ability to penetrate opaque objects without causing harm.
