Summary
| Description |
English: An x-ray far-field interferometer using only phase gratings is based on the phase moiré effect. The mid grating forms Fourier images of the first grating. These images beat with the 3rd grating to produce broad moiré fringes on the detector at the appropriate distance. Phase shifts and de-coherence of the wavefront by the object cause fringe shifts and attenuation of the fringe contrast. |
