Popis:	Abstract This letter discusses an alternative Fourier ptychography algorithm based on the scaled fast Fourier transform propagation. The advantage of this scheme is that it enables a zoom‐in capability of the object spectrum and complex pupil within the synthetic numerical aperture without increasing the overall matrix size. Thus, the high‐resolution complex object and complex pupil are recovered utilising a larger fraction of the elements in their respective representation matrices. Experimental results are presented showing the performance of this scheme against the tradition fast‐Fourier‐transform‐based approach.
