Disclosed is a method of measuring a volume of a liquid provided in at least one receptacle, including the steps of: providing a receptacle having at least one cavity for holding a liquid; providing a plenoptic camera positioned so as to be able to image the surface of the liquid; positioning the receptacle such that the liquid surface faces an objective lens of the plenoptic camera; making at least one plenoptic image of the surface of the liquid by way of the plenoptic camera; determining a surface topography of the liquid on the basis of the at least one image; calculating the volume of liquid based on the measured surface topography and at least one known dimension and/or position of the cavity.

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.
