Resolution determines the level of details the image intensifier can display.
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 per millimeter (lp / mm) that the image intensifier can resolve.
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.
