Abstract: Embodiments relate to an X-ray interferometer for imaging an object comprising: a phase grating for effecting in correspondence with the phase grating geometry a phase shift to at least a part of X-ray incident onto the phase grating; and an absorption grating for effecting in correspondence with the absorption grating geometry absorption to at least a part of X-ray incident onto the absorption grating. The grating period of the phase grating, and the grating period of the absorption grating may be dimensioned such that a detector for X-rays can be placed at a relatively large distance away from the absorption grating such the phase contrast sensitivity of the image of the object detected by the detector remains substantially unaffected.

Abstract: The present invention discloses an interferometer device and method. In embodiments, the device comprises an electromagnetic radiation source emitting radiation having a first mean wavelength ?LE; a phase grating having a first aspect ratio; an absorption grating having a second aspect ratio; and a detector. The electromagnetic radiation source, the phase grating, the absorption grating and the detector are radiatively coupled with each other. The absorption grating is positioned between the detector and the phase grating; the electromagnetic radiation source is positioned in front of the source grating; and wherein the phase grating is designed such to cause a phase shift that is smaller than ? on the emitted radiation. Additional and alternative embodiments are specified and claimed.
