Ptychographic coherent diffraction imaging has been used to overcome the finite space-bandwidth product in classical lens-based microscopy and solve the phase problem in lens-less imaging. While ptychography harnesses data redundancy to recover information about object, illumination and coherence with theoretically unlimited field of view, practically this ability is limited by the computational memory available. Here we present data compression strategies that allow for data reduction by an order of magnitude and promise to find application in memory-limited ptychograpy.
