Noise limit on practical electron ptychography

Ptychography is a wavelength-limited phase retrieval method that promises to provide sub-0.5Å resolution in the electron microscope, even if the lens employed (which is required only to form an illumination spot) can itself only achieve rather modest resolution. The fidelity of a practical specimen...
