The modulation transfer function is the expression of how well the stimulus modulation is transferred to the image. It is the ratio of the modulation of the image, Mi, and the modulation of the ...

Modulation Transfer Function (MTF): A quantitative measure of an optical system's capacity to transfer contrast at varying spatial frequencies from the object to the image.

When you must characterize the resolution and the contrast provided by a lens, you can refer to modulation transfer function (MTF) supplied by the manufacturer for a specific lens. You do not have to ...
