Fourier operator imaginary part
This is the imaginary part of the Fourier operator.
The Fourier operator is a continuous version showing the Fourier transform as Fredholm kernel of the 2nd kind, as the limiting process of a DFT matrix in the limit as the size of the matrix approaches infinity by infinity, so that it goes from discrete (DFT) to continuous Fourier transform.
I made this image for my masters thesis which was on the subject of the chirplet transform, since I also wanted to understand and conceptualize the Fourier transform in new ways, prior to building upon it to extend beyond Fourier and wavelet transforms to chirplet transform.
