Virtual Photodetectors: Building Your Own Detector

Facebook X LinkedIn Email
No one detector solves all detection tasks, but virtual photodetectors provide flexibility to address customer needs.

Andy Whitehead, Southern Vision Systems Inc.

Photodetectors are available in multiple configurations, with point, quadrant, linear and 2-D arrays being among the better known. These devices offer optimal performance for dedicated tasks, and they require processing and digitizing electronics specific to each detector. The profusion of commercially available products can be intimidating when one sets out to solve a detection task. Factors such as spectral response, bandwidth, signal-to-noise ratio, amplifier noise, detector area and sensitivity frequently are traded off one against the other. Virtual photodetectors replace multiple...Read full article
