With a commercially available energy-resolving single-photoncounting detector we investigated how broadband radiation affects the performance of a multi-modal edge-illumination phase-contrast imaging system. The effect of X-ray energy on phase retrieval is presented, and the achromaticity of the method is experimentally demonstrated. Comparison with simulated measurements integrating over the energy spectrum shows that there is no significant loss of image quality due to the use of polychromatic radiation. This means that, to a good approximation, the imaging system exploits radiation in the same way at all energies typically used in hard-X-ray imaging. date: 2015-06-15 date_type: published publisher: OPTICAL SOC AMER official_url: http://dx.doi.org/10.1364/OE.23.016473 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1035488 doi: 10.1364/OE.23.016473 lyricists_name: Basta, Dario lyricists_name: Diemoz, Paul lyricists_name: Endrizzi, Marco lyricists_name: Kallon, Gibril lyricists_name: Olivo, Alessandro lyricists_name: Vittoria, Fabio lyricists_id: BASTA83 lyricists_id: PCDIE01 lyricists_id: MENDR57 lyricists_id: GNKAL68 lyricists_id: AOLIV86 lyricists_id: VITTO07 full_text_status: public publication: Optics Express volume: 23 number: 12 pagerange: 16473-16480 pages: 8 issn: 1094-4087 citation: Endrizzi, M; Vittoria, FA; Kallon, G; Basta, D; Diemoz, PC; Vincenzi, A; Delogu, P; ...
