Interrogating Terahertz with Light

Yvonne Carts-Powell

A new scheme developed by researchers encodes the phase and amplitude information of terahertz waves onto ultraviolet light that can be detected from a distance and from almost any angle.

A method of detecting terahertz waves from 10 m away brings THz imaging closer to viability for security and environmental applications.
