這張測試卡專門設計為范圍在2-0.5線對每毫米高分辨率的測量。

?？聢D案由水平、垂直以及這兩種類型的對角線分辨率BW塊位于5x5個模塊在兩個不同的測試圖表中。

The chart is designed to do resolution measurements in a range of 2 - 0.5 linepairs per millimeter.

Foucault patterns with horizontal, vertical and both types of diagonal resolution bw-bars are located in a matrix structure of 5 x 5 pattern on two different chart sheets.
