ISO-12233 Low Contrast Edge SFR Chart (QA-72C)
This test pattern is an image evaluation tool for determination of resolving power, limiting resolution and spatial frequency response (SFR) of digital image systems at a low contrast signal point. The central OECF gray scale patches can be used to evaluate linearity. It is as specified in ISO-12233:2014, Annex C.
The ISO-12233 Low Contrast Edge SFR chart with 80:1 OECF Patches contains a variety of test pattern elements and is imaged on photo paper Users are advised to refer to International Standard ISO-1233 for a detailed explanation of the target’s features and their use
