2.1.2 On the optical transfer function

The term
as it appears in Equation 10
(and various others) can be further optimised if a theoretical OTF is used.
An experimentally obtained OTF requires its Fourier transform to be
calculated in order for it to be convoluted with the smoothing function ^{4}, this requires both memory and time. However, if a theoretical equation is
obtained for , then the entire term
may
be evaluated theoretically. This will give an equation that can be used in the
algorithm, in order to deconvolute Equation 10.
Thus, a substantial amount of time and memory can be saved by using a theoretically
computed OTF. Refer to Section 2.2 for details of what
OTF was used.
