Hi,
You can try the radial profile plugin as Divakar suggests. I also
ended up rewriting the radial profile plugin so the x-axis is wave
vector to compare with scattering data. If that is of interest, let
me know.

Dear All,
Sorry for bothering.
I had a 2D TEM image and I already used ImageJ to get a 2D power
spectra. (FFT transform on the TEM image).
The problem is: I wan to average the radial intensity
distribution of all the direction on the 2D power spectra to get a
1D power spectra. That is to say, how to extract a 1D magnitude of
the 2D transform. So, I am wondering is there such a plugin to
average over the azimuthal angel to yield the radial power spectra?
Thanks a lot and your respons will be well appreciated!
Regards
Ben
