MTF (Horizontal & Vertical)
DxO Analyzer includes a slanted-edge, "checkerboard", chart for measuring MTF in both horizontal and vertical directions, across the entire image field. The same test image can be used for measuring astigmatism, longitudinal chromatic aberrations, and ringing. In addition, the most recent version of DxO Analyzer software compensates for chart-limited MTF.
Ringing & Color Fringing
Using edge profiles on its ISO #12233-compliant MTF chart, the Optics Module measures ringing artifacts to help you evaluate and tune your sharpening algorithms. The Optics Module also includes a custom Color Fringing transmissive chart that provides measurements of color inaccuracies caused by chromatic aberration − that are especially visible in highly saturated areas.
Effective Focal Length
By measuring the relative magnification of a field of dots across a test chart, DxO Analyzer measures the Effective Focal Length of your lens across its entire image field.
Flash: tests are also provided in the Optics module, helping you evaluate your flash solutions for both Uniformity and accuracy of White Balance.
Distortion & Lateral Chromatic Aberration
A high-fidelity IEEE-CPIQ "dot" chart provides the basis for measuring both geometric distortion and lateral chromatic aberration as they vary by field radius. Results are displayed in table, chart and graphics formats.
