Figure 1. Simulation of 2D structured illumination with fluorescent beads.

Figure 1

(a) Wide-field image. (b) ISIM reconstruction. (c) Logarithm of the ISIM power spectrum: Inline graphic. (d) Cross-correlations of extended domains with the central one, Inline graphic, produce a sharp peak due to their information overlap. The peak provides an estimate of the reconstruction parameter Inline graphic. The regions where the peak appears are enclosed in the white box, top left corner insets show zooms of those regions.
