['1. A detector arrangement for an X-ray phase contrast system (5), the detector arrangement (1) comprising: - a scintillator (11); - an optical grating (12); and - a detector (13); - wherein the optical grating (12) is arranged between the scintillator (11) and the detector (13) and is configured to be electronically adjustable; wherein the scintillator (11) converts X-ray radiation (2) into optical radiation (3); wherein the optical grating (12) is configured to be an analyzer grating being adapted to a phase-grating (21) of an X-ray phase contrast system (5) and -  characterised in that an optical path between the optical grating (12) and the scintillator (11) is free of focussing elements for optical radiation.']
