We present a methodology for the extraction of the spatial Fourier components of the magnetization profile for an array of nanosized magnetic objects, from diffracted magneto optic Kerr effect measurements. The field dependent magnetization configuration in the unit cell is retrieved by inverse Fourier transform and compared with the predictions of micromagnetic simulations. The comparison demonstrates that the methodology is a powerful optical tool for lens-less diffraction-limited optical imaging of the collective magnetic behavior of nano-structures.
