Supposing i have a 1-D or 2-D data...how do i get the spatial frequencies from the FFT expression ( FFT results in a spectrum plotted against sample count)..

The Fourier component corresponding to index j has j-1 cycles within the length of the original data.
If there are N data points, the component corresponding to index j has the same frequency as the component corresponding to index N-j+2.
