Researchers have developed a highly sensitive method for detecting hotspots in the environment, such as bushfires or military threats, by harnessing the focusing power of meta-optical systems. The key ...

Infrared sensors, which act as the "seeing" component in devices such as LiDAR for autonomous vehicles, 3D face recognition systems in smartphones, and wearable health care devices, are regarded as ...

Abstract: A silicon-based image sensor is proposed, incorporating plasmonic diffraction gratings tailored to chief ray angles (CRAs), to enhance near-infrared (NIR) sensitivity improvement over a ...

Abstract: In the realm of smart buildings, the deployment of Internet of Things (IoT) devices, particularly long-range low-power networks (LoRa)-based infrared (IR) sensors, has become increasingly ...
