Improving the low-dose performance of aberration correction in single sideband ptychography
Songge Li, Nicolas Gauquelin, Hoelen L. Lalandec Robert +5
The single sideband (SSB) framework of analytical electron ptychography can account for the presence of residual geometrical aberrations induced by the probe-forming lens. However,…

Phase offset method of ptychographic contrast reversal correction
Christoph Hofer, Chuang Gao, Tamazouzt Chennit +2
The contrast transfer function of direct ptychography methods such as the single side band (SSB) method are single signed, yet these methods still sometimes exhibit contrast revers…
