Patent

CA 2728601

The invention relates to a method for imaging a surrounding area (4) on a detector (8) of a detector device (6) in which an optical system (22) produces an imaging beam path (32), and a panel (20), which is arranged in the imaging beam path (32), shadows a subarea of the image of the surrounding area (4) on the detector (8). In order to allow an object which is dazzling the detector device (6) to be masked out and nevertheless to allow the surrounding area to be monitored, it is proposed that the panel (20) is subdivided into a plurality of segments (34) which can be operated individually, and segments (34) which are associated with the subarea are selected and operated, and are in this way heated, and the transmission of the selected segments (34) is reduced by the heating throughout the frequency range in which the detector (8) is sensitive, and the selected segments (34) of the panel (20) shadow the subarea of the image.
