MTF

The modulation transfer function (MTF) measures the ability of the device to differentiate spatial frequencies. The

MTF value represents the contrast restitution for the corresponding spatial frequency, hence describes the

contrast attenuation. It is a sharpness indicator that quantifies to what extent the image sensor can capture and

discriminate tiny detailed contrast of an object in the field of view.

The figure below presents the on-axis MTF, measured in a 100x28 pixels ROI with the slanted-edge method. Note

that in the following figure, Ny is the spatial Nyquist frequency.
