镜头分辨率和阴影测试 测试卡

TE268 is designed for resolution and sharpness measurements. 25 sinusoidal modulated Siemens stars, 16 slanted edges at four different contrasts, four colored dead leaves structures and rope structure images are placed on the chart. A very detailed analysis over nine different image heights is possible with this chart. The chart has an aspect ratio of 4:3 (image size of 810x1080 mm) or 3:2 (image size of 810x1215 mm). It is suitable for systems from 2 MP up to 180 MP.
