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 ...

Ag 2 Te colloidal quantum dot SWIR photodiodes on the left and solution-processed Ag 2 Te quantum dots on the right. The frequency regime lying in the shortwave infrared (SWIR) has very unique ...

The visible light spectrum that humans perceive spans only a small portion of the electromagnetic spectrum — roughly 430 to 750 THz, corresponding to wavelengths of ~400-700 nm. Just beyond this range ...

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 ...

An Infrared close object sensor installed on an industrial vehicle detects objects or pedestrians located in a hazardous area. When it detects a problem an audio/visual indicator makes an alert, that ...
