The optical transfer function (OTF) of an optical system specifies how different spatial frequencies are handled by the system.

What is the Fourier transform MTF?
MTF is defined as the Fourier transform (FT) of the point spread function (PSF). This concept applies to a linear system that is shift invariant. In practice, MTF is usually measured in two orthogonal directions using FT of the line spread function.
What does the modulation transfer function tell you?
The modulation transfer function (MTF) describes the ability of a detector to retain the contrast (signal amplitude) of an object. It also measures how much spatial frequency is transferred from the object to an image 8. This is because each detector has its own limiting spatial resolution.
What does MTF mean in imaging?
The modulation transfer function, or MTF, is a parameter used to evaluate the performance of a lens. MTF provides a quantitative and standardized way to characterize optical systems, so the metric is used by optical designers and microscopists alike to compare lenses and determine the ideal one for an imaging system.
What does MTF stand for XRAY?
The modulation transfer function (MTF) is the most widely accepted measure of the spatial resolution response of medical x-ray imaging detectors and has proved to be a valuable tool for determining and comparing detector performance.
