PbS was one of the first materials used for electrical diodes that could detect electromagnetic radiation, including infrared light. As an infrared sensor, PbS directly detects light, as opposed to thermal detectors, which respond to a change in detector element temperature caused by the radiation. A PbS element can be used to measure radiation in either of two ways: by measuring the tiny p… Splet17. mar. 2024 · Host Joan Cartan-Hansen and her guests, Kathryn Devine, Associate Professor of Physics, College of Idaho and Christopher Saunders, Lecturer, department of …
