USAF分辨力测试卡( USAF resolution test chart)是符合MIL-STD-150A标准的分辨力测试图案,由美国空军于1951年创建。这种测试图仍广泛地应用于测试光学成像系统(如显微镜和相机)的分辨能力。这种图案包括几组由三条短线构成组合,短线的尺寸从大到小。成像系统无法辩明的最大短线组为其分辨能力极限。 通常格式包括3层...

The resolution limit of a system is found by examining an image of the resolution test chart. Locate the Element of highest frequency where either horizontal or vertical lines are not indistinct. Note that the horizontal limit of resolution may indicate a different frequency than the limit of ver...
