Beam-tracking relies on creating micro-beamlets of radiation by placing a structured mask before the sample, and analysing them by using a detector with sufficient resolution. The system is used in tomographic configuration to measure the three dimensional distribution of the linear attenuation coefficient, difference from unity of the real part of the refractive index, and of the local scattering power of specimens. The complementarity of the three signals is investigated, together with their potential use for material discrimination. date: 2018-04 date_type: published publisher: IOP official_url: https://doi.org/10.1088/1748-0221/13/04/C04008 oa_status: green full_text_type: other language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1545262 doi: 10.1088/1748-0221/13/04/C04008 lyricists_name: Diemoz, Paul lyricists_name: Endrizzi, Marco lyricists_name: Hagen, Charlotte lyricists_name: Kallon, Gibril lyricists_name: Olivo, Alessandro lyricists_name: Vittoria, Fabio lyricists_id: PCDIE01 lyricists_id: MENDR57 lyricists_id: CKHAG69 lyricists_id: GNKAL68 lyricists_id: AOLIV86 lyricists_id: VITTO07 actors_name: Olivo, Alessandro actors_id: AOLIV86 actors_role: owner full_text_status: public publication: Journal of Instrumentation volume: 13 article_number: C04008 event_title: 24th International Congress on X-Ray Optics and Microanalysis (ICXOM24) event_location: Trieste, Italy event_dates: 25 September 2017 - 29 September 2017 institution: 24th International Congress on X-Ray Optics and Microanalysis (ICXOM24) citation: Vittoria, FA; Endrizzi, M; Kallon, GK; Hagen, CK; Diemoz, PC; Zamir, A; Olivo, A; (2018) Beam tracking phase tomography with laboratory sources.
