Using a specialized MRI sensor, engineers have shown that they can detect light deep within tissues such as the brain. Using a specialized MRI sensor, MIT researchers have shown that they can detect ...

I want to add an analog ambient light detector to one of my electronics projects. To do that, I picked the TEMT6000 ambient light sensor. TEMT6000 is a silicon NPN epitaxial planar phototransistor in ...

An image from a corrugated quantum well infrared photodetector (C-QWIP) shows traffic flowing along a highway near Kings Island theme park in Mason, Ohio. Note the white "hot" spots on the tires and ...

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

All photoelectric sensors use a light source to signal the presence or absence of an object. So one method of classifying these sensors is by how they use that light. The first photoelectric sensors ...
