Image intensifiers allow the amplification of visible images up to a level, where single quanta of light can be seen at the output of the device. In contrast to semiconductor sensors, the physics of the detection process hinders most of the thermally generated electrons to be amplified. Therefore the dark current of these sensors is drastically reduced, which makes them a prime candidate for ultra-low light environments.
Another unique feature of the detection process is the possibility to stop the signal generated by incoming photons to be amplified and detected in about 1 ns. Thus, these detectors can be used for high speed imaging down to a timespan of ~ 3ns. Therefore they have to be driven by an appropriate pulse generator (ProxiGate).
The spectral response can be tuned by selecting different photocathode materials and parameters (->Verweis auf Bild mit PK Empfindlichkeiten unter Configuration Parameters). Photocathodes with higher sensitivity in the red part of the spectrum have higher noise than those who are only sensitive in the blue/green part.
