Figure 3
Simulated intensity patterns of a plane wave which passes through a PMMA sphere and propagates 1 m in free space to the imaging plane. (a) Monochromatic incident wavefield with energy 15 keV; (b) polychromatic incident wavefield with energy range 10–30 keV; (c) partial spatial coherence due to an extended source applied on (b) (vertically five times larger coherence than horizontally); (d) short exposure time (the sphere moves horizontally by one pixel per camera exposure time) and the associated strong shot noise applied on (c); (e) also shot noise application on (c) but with 50-times longer exposure time than in (d), thus the SNR is larger but there is motion blur by 50 pixels. Grayscale is adjusted for every image separately. |
