The ability of an imaging system to distinguish small details and separate objects in an image, often measured in lp/mm.

Line pair per mmlpmm

Modulation Transfer Function (MTF): A function that describes the ability of an imaging system to transfer various levels of detail from the object to the image, often linked to lp/mm measurements.

Line pairs per millimeter (lp/mm) is a measurement used to describe the spatial resolution of imaging systems, indicating how many pairs of contrasting lines can fit within one millimeter. This metric is crucial for assessing image quality, as higher lp/mm values signify better detail and clarity in the images produced. It is directly related to the capability of an imaging system to resolve fine details, playing an essential role in applications like radiography, microscopy, and digital imaging.
