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 ...

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 ...

How to stabilize transimpedance amplifiers used to convert photodiode current output to voltage. Fig 1. Shown is a basic TIA circuit used in dual-supply systems. Fig 2. Figure 1’s TIA circuit was ...

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

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 ...

This circuit was developed to aid manufactures of optical equipment in using linear detectors arrays with their optical setup without requiring specialised knowledge of electronics. These circuits ...
