Figure 4
(a) Energy resolving power comparison of the CIA-VCGM and the CIA-VPGM with the grating line density as 800 lines mm−1, 1000 lines mm−1 and 1200 lines mm−1, where the CIA-VPGM is optimized with different energy sets. The RP without the defocus (black squares) is shown as a benchmark. (b) RP degradation caused by the defocus aberration. |
