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.
