前言多年来,我们总是用测量影象的最高可分细节来评价影象的质量。用这种方法仅能给出成象系统的极限分辨率(单位LP/mm 或 LP/cm)。一般说,人们在影象上能分清的线对数越多则显示的影象细节越清楚。但这种极限分辨率是因人而异
For many years we have always evaluated the quality of the image with the highest possible detail of the measured image. Only the limit resolution (in LP / mm or LP / cm) of the imaging system can be given in this way. In general, the more line pairs people can distinguish on the image, the clearer the details of the image displayed. However, this limit resolution varies from person to person
