Experimental demonstration of resolution enhancement. (a) The object without addition of optical aberrations (scale bar=56 μm). (b) A degraded image of the bars. (c) The reconstructed image. (d) The PSF that was used for image reconstruction (scale bar=5.4 μm). (e) Comparison of the intensity profile, marked by dashed line in a–c. Only the PEPSI-based deconvolution resolves the first bar—the first local minimum, circled. (f) The PEPSI-based ML image reconstruction, obtained by PSF estimation of the intrinsic aberrations of the optical setup. The initial image for the reconstruction was a and speckles were measured without the phase plate. All images share the same gray scale. (g) The PSF used for image reconstruction in f. Scale bar=3.6 μm.
