Fourier back to real space [message #78081]

Hi,

I have an images with periodic stripes with various orientation which
I would like to find the periodicity of. I've Fourier transformed the
image and found the peak in the transform (via a radial average) so I
have the q value (in I assume pixels^-1) corresponding to my stripe
periodicity. I now need to get a real space value out but I'm lost as
to where the factors of 2pi etc go. Can anyone point me in the right
direction? I've read the help files online but I'm still horribly
confused.

Many Thanks,

Anne
