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 ...

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

Although advances in photonics and electronics are making it easier and cheaper to implement a light detection and ranging (LIDAR) system, the analog front-end receiver interface still presents many ...

ActLight SA and A*STAR Institute of Microelectronics (IME) of Singapore have successfully built the "Dynamic Photodiode" using A*STAR IME's photonics technology. ActLight's patented Dynamic Photodiode ...

This is a preview. Log in through your library . Abstract A new quantum sensor for measuring photosynthetically active radiation (PAR) was designed using a gallium arsenide photodiode. This sensor 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 ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...
