Additional Filtering
If additional filters are applied, then can also write out what resolution will be in these cases
(13.9)
If
for all
then
(13.10)
BUT assume
for all
so
is always larger than
.
(13.11)
other definitions of resolution exist
Full Width at Half Maximum of the point spread function
Full Width at Tenth Maximum of the point spread function
Look for first zero crossing of function (won't work for all).
Some
giving fixed area less than the total area under filter
