Abstract
A method and apparatus for ptychographic imaging is described. Typically a high number of pixels (after binning) is needed to obtain a high quality reconstruction of an object. By using calculation planes with more nodes (for example 512×512 nodes) than the number of pixels of the detector, a high quality reconstruction of an object can be made, even when using for example a 16 segment detector, or a 32×32 pixel detector. Although the reconstructed object shows less resolution (“sharpness”), all features are there.
