Assignment of the numeric grade of AIM DPM-1-2006 to the quality levels
Grade 4 3 2 1 0 Comment
Axial non-uniformity (AN_) ≤6% ≤8% ≤10% ≤12% >12% Calculation different from ISO
15415
Cell contrast (SC_) ≥30% ≥25% ≥20% ≥15% <15%
Cell modulation (MOD) This measurement is made in a three-stage process.
There is no direct correlation between the
intermediate results and the quality grade.
Fixed pattern damage (FPD) This measurement is made in a three-stage process.
There is no direct correlation between the
intermediate results and the quality grade.
Grid non-uniformity (GN_) ≤0.38 ≤0.50 ≤0.63 ≤0.75 >0.75 Calculation different from ISO
