How transimpedance amplifiers are used in fiber-optic communications, laser rangefinders, and LiDAR systems. How avalanche photodiodes enhance TIA performance. Application-specific design and topology ...

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 layered graphene and chromium oxychloride device functions as a broadband optical synapse, detecting visible to deep infrared light and learning image orientation through built-in memory. (Nanowerk ...
