允许从任何点在这个圆的周长上多个目标的MTF测量样品。
分辨率测量可以用Imatest的星图模块进行。
不如Edge-SFR分析有些图形理敏感。
可以改善一些测量重复性噪音。
比较低对比度垂直+水平倾斜的边缘。
对比双曲锲形位置变化不是很敏感。
允许测量各个角度的高分辨率，包括垂直、水平、矢状面和切向面。
自动检测登记标志图案。
尺寸
尺寸选项 | 国际标准单位 | 纸张大小 |
1x | 250 mm × 333.33 mm | 9.84" × 13.11" |
1.5x | 375 mm × 500 mm | 14.76" × 19.66" |
2x | 500 mm × 666.67 mm | 19.69" × 26.22" |
3x | 750 mm × 1000 mm | 29.53" × 39.34" |
Target allows multiple samples of MTF measurements to be taken from any point within the circumference of the circle.
Resolution measurements can be made with Imatest's Star Chart module
Less sensitive to some image processing than Edge-SFR analysis
Resistant to noise which can improve some measurement repeatability
Includes low-contrast vertical + horizontal slanted edges for comparison
Less sensitive to changes in position than the hyperbolic wedge
Enables resolution measurements at all angles including vertical, horizontal, sagittal and tangential
Includes registration mark patterns for automatic detection
