I was working on some dark field filters and I was wondering if you could substitute the black spot in the centre of a dark field filter for a completely black filter with a light passing hole in the middle. Sort of an inverted dark field filter.
I seem to remember reading something like this involving conjugate images when I was doing Fourier theory a while ago.
Would the filters have the same effect? Or are conjugate images Fourier transforms of each other?
