Results for real data. The left and right columns are the Siemens star chart and ink toner, respectively. Typical diffraction intensity patterns are shown at the top. The amplitude images of the object, phase images of the object and probe reconstructed by (a) ePIE, (b) rPIE and (c) CRISP are shown in the left, middle and right, respectively. (d) and (e) are histograms of τij for (d) the Siemens star chart and (e) ink toner. The blue bins are ePIE, the yellow bins are rPIE and the red bins are CRISP. For the Siemens star chart, the median of τij was 1.4 × 10−2 for ePIE, 1.5 × 10−2 for rPIE and 1.1 × 10−2 for CRISP; the variance of τij was 5.8 × 10−6 for ePIE, 8.5 × 10−6 for rPIE and 8.0 × 10−7 for CRISP; the RF factor at the final iteration was 0.422 for ePIE, 0.499 for rPIE and 0.423 for CRISP. For ink toner, the median of τij was 4.5 × 10−3 for ePIE, 9.3 × 10−3 for rPIE and 4.2 × 10−3 for CRISP; the variance of τij was 4.2 × 10−7 for ePIE, 2.6 × 10−6 for rPIE and 1.7 × 10−7 for CRISP; the RF factor at the final iteration was 0.237 for ePIE, 0.299 for rPIE and 0.230 for CRISP. Bars in (c) indicate 4 µm, and that in the inset 1 µm. |
