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 ...

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 ...

Imec, the nanoelectronics and digital technologies research hub, has announced the successful integration of a pinned photodiode structure into thin-film image sensors. With the addition of a ...

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 ...
