被引用回数：17 パーセンタイル：67.09(Physics, Multidisciplinary)The possibility of phase-contrast imaging of nanostructures has been analyzed with the use of solid targets irradiated by femtosecond laser pulses as a spatially coherent soft X-ray source and a LiF crystal as an X-ray detector having both the submicron spatial resolution in a wide field of view and a high contrast. It has allowed to obtain high-quality phase-contrast X-ray images of foils with various chemical compositions and a thickness of about 100 nm.

被引用回数：26 パーセンタイル：73.77(Optics)Elemental sensitivity in soft X-ray imaging of thin foils with known thickness is observed using an ultrafast laser-plasma source and a LiF crystal as detector. Measurements are well reproduced by a simple theoretical model. This technique can be exploited for high spatial resolution, wide field of view imaging in the soft X-ray region, and it is suitable for the characterization of thin objects with thicknesses ranging from hundreds down to tens of nanometers.
