Ptychography image reconstruction. (a, b) Reconstructed image of a 1 µm × 3 µm magnetic pattern obtained by scanning the sample and using left (a) and right (b) circular polarization. (c) Intensity profiles along the lines drawn in (a) and (b). (d) Reconstructed image of magnetic domains in a ring 2.5 µm in diameter and 170 nm wide, obtained by scanning with piezo motors and using left circular polarization. (e) The red curve shows the intensity profile along the red line in (d); the green curve is the convolution between a 170 nm-wide box function and a Gaussian of 75 nm σ radius. (f) Intensity profile along the magenta line in (d) showing intensity modulations corresponding to the magnetic domains within the ring.
