Phase-Contrast Imaging in a Polychromatic X-ray Beam at a Laboratory Source

An experimental setup for carrying out measurements using the X-ray phase-contrast technique on a polychromatic laboratory source is proposed. A standard Mo-anode X-ray tube at an accelerating voltage of 45 kV is used in the experiments. A slit aperture is used to form a conical beam. The phase-contrast effect is demonstrated on a series of objects. The proposed technique of phase-contrast measurements can be used in tomographic experiments.
