    Abstract: In at least one embodiment of the method for controlling an illumination of an object, the object is illuminated by a first radiation source during the method. A second radiation source is provided, the latter being configured to illuminate the object in addition to the first radiation source. The method comprises a step A), in which a first measurement signal is captured, wherein a change in the first measurement signal is representative for a change in a first radiation property of radiation striking the object. In a step B), the second radiation source is controlled, on the basis of a detected change in the first measurement signal, in such a way that the second radiation source illuminates the object and the change in the first radiation property of the radiation striking the object is counteracted.
