Abstract
The invention relates to a grating device for phase contrast and/or dark-field imaging of a movable object, an interferometer unit, a phase contrast and/or dark-field imaging system, a phase contrast and/or dark-field imaging method, a computer program element for controlling such device and a computer readable medium having stored such computer program element. The grating device comprises a grating unit, an actuation unit, a motion detecting unit, and a control unit. The actuation unit is configured to position the grating unit in different sampling positions relative to the moveable object. The motion detecting unit is configured to detect a motion of the movable object. The detected motion of the moveable object may be a repetitive motion. The control unit is configured to control the actuation unit to position the grating unit in the different sampling positions based on the detected motion of the movable object.
