Maybe this is of any help :




"The maximum spatial resolution is described as ability to separate patterns of black and white lines and it is given in line pairs per millimeter ([lp/mm]). As theoretical limit it is described in the literature and com-prehensive that the maximum resolution is achieved if one black line is imaged on one pixel while one white line is imaged to the neighbor pixel."
