Sensing in the mid infrared spectral range is highly desirable for the detection and monitoring of different gases. We hereby propose a CMOS compatible silicon-based sensor that operates at (3.5–10 μm ...

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 ...

Detecting infrared light is critical in an enormous range of technologies, from remote controls to autofocus systems to self-driving cars and virtual reality headsets. That means there would be major ...

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

The Defense Advanced Research Projects Agency (DARPA) has announced a new program which seeks to enable quantum-level infrared (IR) detection at room temperature. The IR spectrum is a vast information ...

Cost-effective sensors from the University of Bonn are measuring water levels along rivers and coastlines in Africa and the Pacific region. Using a low-cost sensor and GNSS Interferometric ...
