Caption
The terahertz imager features a microchip (see inset) and a reflector that increases the imaging distance and quality and reduces power consumption. The microchip emits radiation beams in the terahertz range (430 GHz) of the electromagnetic spectrum from pixels no larger than a grain of sand. The beams travel through obstacles that optical light cannot penetrate and bounce off objects and back to the microchip, where the pixels pick up the signal to create images.
