SFRplus Chart: Chrome on Glass
Testing at Infinity can be simulated by using this chart as a reticle in a telescope along with a collimating light source.
The Unitone SFRplus test chart can be used with the SFRplus module in Imatest 3.2 or later to measure MTF, lateral chromatic aberration, and distortion. 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:
- Much less wasted area
- The ability to produce a map of sharpness over the sensor surface
- Better measurement accuracy due to the lower contrast
- Full support for automated testing.
