Fig. 5: Numerical demonstration of multiple-shot coherent diffraction imaging.

a Selected frames of the model at glycerine concentration of 90%w/v and temperature of 283 K. Phase (upper) and absorption (lower) images of the object transmission functions averaged over the frame time are shown. The illuminated area is indicated with the broken circles. Phase (upper) and absorption (lower) contrast object frames reconstructed using b multiple-frame ptychographic iterative engine with total-variation regularisation (mf-PIE-TV), c mf-PIE, and d extended PIE (ePIE). e Temporal-averaged Fourier ring correlation (FRC) curves for mf-PIE-TV (red), mf-PIE (blue), and ePIE (black). The broken line indicates a threshold of 0.5 and corresponding spatial frequency. The grayscale is the same as that shown in Fig. 4. The frame numbers are indicated in the phase images. Scale bars indicate 1 μm.
