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

Cheaper, larger and better infrared detectors grown on silicon wafers could give more scientists access to infrared astronomy and further spur the hunt for exoplanets and the study of the universe’s ...

Polarization, as a primary physical quantity of light, is of great interest to almost all optical sciences and technologies. Along with linear polarization detection, circular polarization (or light ...

Jülich researchers, together with Italian and German colleagues, have developed a particularly cost-effective infrared detector that can be easily integrated into existing camera chips and smartphones ...

(Nanowerk News) What do motion detectors, self-driving cars, chemical analyzers and satellites have in common? They all contain detectors for infrared (IR) light. At their core and besides readout ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Researchers from Rochester Institute of Technology’s Center for Detectors received new funding from the National Science Foundation to continue developing infrared detectors for the next generation of ...

The telescope 'time machine' will deliver 13.5 billion years of cosmic history. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The newest deep ...

Detecting light beyond the visible red range of our eyes is hard to do, because infrared light carries so little energy compared to ambient heat at room temperature. This obscures infrared light ...

This circuit can be built from readily available low-cost components, some of which may even be hiding in your junkbox! The indicated value of 22 Ω for resistor R1 causes an average current of about ...
