SFRreg Test Target
The SFRreg test target consists of a slanted-edge 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 Imatest 4.2.
 
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 large

  • Ultra-wide Field of View tests (>170°) where a flat target cannot reach the outer field

  • Autofocus tests where a single frame can contain several targets placed at different distances

The SFRreg module also supports collimators which project test targets that allow you to test a camera focused at long distances up to infinity in compact environments.
