SFRreg Test Chart


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 beginning with Version 4.2

Distortion Note: High amounts of distortion where the target may be compressed so that the major axis is 50% larger than the minor axis may have issues with autodetection. Pre-distortion may be necessary for these cases.

SFRreg Test Chart




Download PDF Info Sheet 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

Available substrates: High Precision Film, Reflective Inkjet and Transmissive Inkjet. Inkjet charts are available in either 10:1 or 4:1 contrast ratios.
