Ion microwave imaging emitter
Web11 sep. 2024 · An IR emitter shoots out a beam of light, facing an in-line receiver. If nothing is in the way, the receiver sees a signal. If the receiver fails to see an IR beam, it detects that an object is between the emitter and the receiver, and therefore present in the monitored area. Web11 apr. 2024 · In (e) monolayer CVD hBN, discrete bleaching steps are observed, where each step may correspond to an individual emitter. Credit: Communications Materials (2024).
