Claim One:
1. A method for examining an object with an X-ray recording system for phase contrast imaging including at least one X-ray emitter for generating a quasi-coherent X-ray beam as a first component, an X-ray image detector including pixel elements arranged in a matrix, a diffraction or phase grating arranged between the object and the X-ray image detector, and an analyzer grating associated with the phase grating for generating an intensity pattern or interference pattern, at least two of the X-ray image detector, phase grating and analyzer grating being fixedly connected to one another and form a second component, the method comprising: moving the components, during an X-ray image recording the components, relative to one another with the lateral displacement by displacement distances; generating the X-ray image recording during the displacement from n partial images, such that a total exposure time of the X-ray image recording is made up of a sum of partial exposure times; determining, in each of the partial images, an intensity in each pixel; determining a position of the second component relative to the first component for each recording of the partial images; and determining image information from the partial images and the displacements.
