Abstract

A device and method for reading an exposed imaging plate generate read-out light and utilize a deflection unit to direct the read-out light in a scanning movement over the imaging plate. The deflection unit has a micromirror to deflect impinging read-out light towards the imaging plate. The micromirror can swivel about a first swivel axis and about a second swivel axis distinct from the first. A detector unit detects fluorescent light emitted from the imaging plate at locations where the read-out light impinges. An evaluating unit evaluates signals received from the detector unit and builds up an image that is stored in the imaging plate. The evaluating unit takes into account, when evaluating the signals received from the detector unit, that points on the imaging plate are subjected to the read-out light variably often and/or for variable time lengths while the micromirror oscillates about the first and the second swivel axis.
