Thank you for replying, I was afraid that was the case. So on the conjugate images point, are the two filters in this case Fourier transforms of each other? Why are they called conjugate images? Is the link between the two simply that they appear as inverted forms of each other or is there...
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...
I've been working on this problem as well, and I think that the expression for the energy should have a k term
E=\frac{(\mu\omega^2)}{2}(x_0^2+y^2_0)+\frac{k^2}{2}}(x_0^2+y^2_0)
Because if you put the terms for xo and yo in for r I can't see why the k term would disappear. Also for your...
