The '''Opticaloptical Transfertransfer Functionfunction''' ('''OTF''') describes the spatial (angular) variation as a function of [[spatial frequency|spatial (angular) frequency]]. When the image is projected onto a flat plane, such as photographic film or a solid state detector, spatial frequency is the preferred ___domain, but when the image is referred to the lens alone, angular frequency is preferred. OTF may be broken down into the magnitude and phase components as follows:

:<math>\mathbf{OTF(\xi,\eta)}=\mathbf{MTF(\xi,\eta)}\cdot\mathbf{PTF(\xi,\eta)} </math>
