SFRreg Charts:
Required Description:
The SFRreg test target consists of a slantededge quadrant pattern enclosed within a circle. It is used for measuring MTF and lateral chromatic aberration. A test image typically contains several targets that are automatically detected and analyzed by the SFRreg module.
SFRreg targets can be placed at arbitrary positions and angles to accommodate a wide variety of test cases:
● Long distance tests where conventional charts would be impractically long
● Ultrawide Field of View tests (>180) where a flat target cannot reach the outer field
● Autofocus tests where a single frame can contain several targets placed at different distances.d
