In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Photodiodes are used in a wide variety of applications to transform light into a current or voltage. These range from solar cells to optical data networks, from precision instruments to chromatography ...

In this section we shall discuss the interface between a photosensor and its associated electronics. There are really just two photocell applications – light measurement, and the reception of ...

Researchers developed a single photodiode sensor that detects full-color light using perovskite materials, impedance data, and machine learning algorithms. (Nanowerk Spotlight) Conventional ...

Panasonic's new Lumix DMC-GF5 incorporates the newly developed 12.1-megapixel Live MOS sensor which features high sensitivity signal processing. Both photodiode circuit and readout circuit are also ...

Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons.

Powerful, inexpensive and even flexible when they need to be, organic photodiodes are a promising alternative to silicon-based photodetectors. They are used to improve light sensitivity in cameras and ...

The instinctive reaction when measuring nuclear radiation is to think of a Geiger counter, as the low-pressure gas tube detectors have entered our popular culture through the Cold War. A G-M tube is ...
