Editing Resolution

Resolution determines the level of details the [[Image_Intensifier|image intensifier]] can display. It is usually specified in ''line pairs per millimeter'' (lp / mm).

It is determined by taking a test image formed from a sequence of black lines, with the width and distance between consecutive lines becoming narrower towards the end of the sequence. By measuring at which point in the sequence the line pairs cannot be distinguished from each other anymore, one finds the maximum value of line pairs that the image intensifier can resolve per millimeter of [[Phosphor Screen|phosphor screen]].

== Bright Lights ==
Most image intensifiers suffer from a substantial loss of apparent resolution in brighter environments. As such, some specifications and standards distinguish between low light resolution and high light resolution. That loss is often bigger on filmed (= gen 3) tubes due to the scattering effect of the film.
