Researchers Sandia National Laboratories have developed a nanoantenna-enabled detector that can boost the signal of a thermal infrared camera by up to three times and improve image quality by reducing dark current — a major component of image noise — by 10 to 100 times. A nanoantenna is a nanoscale antenna-like structure that sends and transmits electromagnetic waves.
