The optical transfer function (OTF) of an optical system such as a camera, microscope, human eye, or projector specifies how different spatial frequencies are captured or transmitted. It is used by optical engineers to describe how the optics project light from the object or scene onto a photographic film, detector array, retina, screen, or simply the next item in the optical transmission chain. … WebFigure 3: A slanted-edge MTF test generates MTF information from the line spread function of a slanted edge. This process only works if the contrast transition of the edge target occurs of a scale four times smaller than the Nyquist limit.
