and can
be used with the SFRplus module 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 much
less wasted area,the ability to produce a map of
sharpness over the sensor surface,better
measurement accuracy due to the lower contrast, and full
support for automated testing.
Size
This
chart has an active chart area of 48.3 cm x 26.81 cm (19 in x 10.56 in)
in a total film size of 30.48 cm x 50.8 cm (12 in x 20 in). Bar-to-bar
height is 252 mm (9.92 in).
This
chart is produced with a high-precision, black and white, LVT film
recording process for the best possible density range, low noise, and
fine detail. The edges have an MTF50 >= 10 cycles/mm, which is
about 2 times better than the best inkjet charts. For more information
please take a look at our transmissive chart quality
comparison! The large patterns are fine enough to produce good results
with up to 30 megapixel cameras.
