The SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later to measure MTF, lateral chromatic aberration, distortion, and tonal response. The SFRplus module features fully automated region-of-interest detection. The SFRplus chart offers significant advantages over commonly used charts such as the ISO 12233 chart, including 1) much less wasted area, 2) the ability to produce a map of sharpness over the sensor surface, 3) better measurement accuracy due to the lower contrast, and 4) full support for automated testing.
