GRATING ASSEMBLY FOR INTERFEROMETRIC X-RAY IMAGING

A grating assembly (G0-G2) for interferometric X-ray imaging. The assembly (GA) comprises a carrier sheet (CS) having deposited thereon grating tiles (GT), the said sheet having edge portions (E1-E4) and a thermal expansion coefficient. Distinct from the sheet, there are stabilizer bar members (S1-S...

Summary:A grating assembly (G0-G2) for interferometric X-ray imaging. The assembly (GA) comprises a carrier sheet (CS) having deposited thereon grating tiles (GT), the said sheet having edge portions (E1-E4) and a thermal expansion coefficient. Distinct from the sheet, there are stabilizer bar members (S1-S4) affixed along respective ones of the said edge portions, the stabilizer bar members having substantially the same thermal expansion coefficient as the said sheet. La présente invention concerne un ensemble réseau (G0-G2) pour l'imagerie à rayons X interférométrique. L'ensemble (GA) comprend une feuille de support (CS) sur laquelle sont déposées des tuiles de réseau (GT), cette feuille ayant des parties marginales (E1-E4) et un coefficient de dilatation thermique. Distincts de la feuille, des éléments de barre stabilisatrice (S1-S4) sont fixés le long de chacune de ces parties marginales, les éléments de barre stabilisatrice ayant sensiblement le même coefficient de dilatation thermique que ladite feuille.
