Abstract
New lensless diffractive X-ray technic for micro-scale imaging of biological tissue is based on quantitative phase retrieval schemes. By incorporating refraction, this method yields improved contrast compared to purely absorption-based radiography but involves a phase retrieval problem since of physical limitation of detectors. A general method is proposed in this paper for one step reconstruction of the ray integral of complex refractive index of an optically weak object from intensity distribution of the hologram.
