Abstract
An image of a surrounding area is projected onto a detector of a detector device by way of an optical system that produces an imaging beam path. A screen is disposed in the imaging beam path and the screen shadows a subarea of the image of the surrounding area on the detector. In order to allow an object which is dazzling the detector device to be masked out and nevertheless to allow the surrounding area to be monitored, the screen is subdivided into a plurality of segments which can be operated individually, and segments which are associated with the subarea are selected and operated, and are in this way heated. The transmission of the selected segments is reduced by the heating throughout the frequency range in which the detector is sensitive, and the selected segments of the screen thus shadow the subarea of the image.
