The method involves dividing the diaphragm (20) provided on an image beam path (32) into individual segments. The divided segments of diaphragm are selected and actuated, and are warmed up by supply of optical radiation and electric power to the divided segments, for reducing transmission of selected segments of diaphragm in entire frequency range in which detector is sensitive, so that a portion of image of environment on detector is shaded using diaphragm. An independent claim is included for device for imaging environment using detector device. |
