A team of physicists at the University of Sussex has developed the first nonlinear camera capable of capturing high-resolution images of the interior of solid objects using terahertz (THz) radiation.
Led by Marco Peccianti of the Emergent Photonics (EPic) Lab, Luana Olivieri, Juan S. Totero Gongora, and a team of research students built a new type of THz camera capable of detecting THz electromagnetic waves with high accuracy.
Images produced using THz radiation are called hyperspectral because the image consists of pixels, each one containing the electromagnetic signature of the object in that point.
Lying between microwaves and infrared in the electromagnetic spectrum, THz radiation penetrates materials like paper,…READ MORE
