Line 1:

The '''Optical Transfer Function''' (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:

Line 20:

Phase is critically important to [[adaptive optics]] and holographic systems.

The OTF is the [[Fourier transform]] of the [[Point Spread Function]].
