Named after the Picatinny Arsenal in New Jersey, where it was developed, the rail comprises a series of ridges with a T-shaped cross-section interspersed with flat “spacing slots”. Scopes et al. are mounted either by sliding them on from one…
Photocathode sensitivity is a measure of how well the image intensifier tube converts light into an electronic signal so it can be amplified. The measuring units of photocathode sensitivity are micro-amps/lumen (µA/lm) or microamperes per lumen. This criterion specifies the…
The input surface of an image intensifier tube that absorbs light energy (photons) and in turn releases electrical energy (electrons) in the form of an image. The type of material used is a distinguishing characteristic of the different generations.
