Image Resolution is the ability of an image
intensifier or night vision
system to distinguish between objects close together. Image
intensifier resolution is measured in line
pairs per millimiter (lp/mm) while system resolution is measured
in cycles per milliradian.
For any particular night vision
system, the image intensifier
resolution will remain constant while the system resolution can be
affected by altering the objective or eyepiece optics by adding magnification
or relay lenses. Often the resolution in the same night
vision device is very different when measured at the center of
the image and at the periphery of the image. This is especially important
for devices selected for photograph or video where the entire image
resolution is important.
