Doublw slit experoment and fourier transform

  1. Mar 27, 2013 #1
    is the interference pattern produced by a double slit a one dimensional phase/amplitude Fourier transform?
    and if you did a reverse Fourier transform on it would you get an image of the two slits?

    Basically, yes.
    FT is frequently used in XRay crystallography to help find the structure of a complicated scatterer from its diffraction pattern.

    Maybe. Since the transformation deals with frequencies, though, you would need to plug it in to another equation to get the image.

    Yes, the (scalar) interference pattern is the Fourier transform of the aperture function (transmission as a function of position). A reverse Fourier transform would indeed retrieve the aperture function - this is the principle behind Fourier optics.
