A Cheap Terahertz Camera - IEEE Spectrum via @IEEESpectrum

Animation: Bergische Universität Wuppertal Scanner: The imager detects a terahertz radiation source in real time. Despite its finely tuned antennas and optics, the camera’s sensitivity is fairly low. While the photodiodes in a typical optical CMOS sensor can convert nearly all incoming photons into charge, Sherry says, terahertz photons are so low in energy that his team’s camera needs roughly 100 000 of them to produce a single electron. Sensitivity aside, the development of this video-rate chip, along with other efforts to produce CMOS-compatible detectors, suggests that terahertz detection will soon become more mainstream. “It represents a turning point in terahertz technology,” says Sigfrid Yngvesson , an expert in terahertz detection at the University of Massachusetts Amherst. “We can now look forward to terahertz technology that is less exclusive and less expensive t...
