Photometric Measurement Test Patterns
Modulation Transfer Function (MTF)
For photometric measurement, with its possibility of determining the modulation transfer function (MTF) of an image transmission system, tests have been developed without intermediate spaces between the
individual line pairs or line groups, in order to avoid measuring errors due to neighbouring effects. In order to maintain the same measurement certainty over the total spatial frequency range, after reaching
the highest spatial frequency, the values drop again to the same degree (see tabulated test description).
