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 ...

A research team led by Professor Jiwoong Yang of the Department of Energy Science and Engineering at DGIST has developed next-generation optical sensor technology capable of precisely detecting not ...

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 ...

For Part 1, click here. High-speed optical communications applications have some high-level transimpedance-amplifier (TIA) circuit similarities with laser rangefinders (LRFs) and LiDAR. However, there ...
