Pap smear reconstruction results acquired for different number of lensfree diffraction intensities. (a) Back propagated image from one PSR lensfree hologram. (b), (c), (d) and (e) Multi-height based PSR lensfree phase images from two, three, four and five heights, respectively (same color bar as in (a)). For fair comparison 144 Fourier transform pairs were used in each reconstruction case. (f) 10 × objective lens (0.25NA) microscope image is provided for comparison purposes. The cell’s boundaries are more visible in our phase images, while the absorbing nuclei of the cells are better visualized in our amplitude images as illustrated in Fig. 4.
