A steerable an optical imaging system, in particular for seeking heads in the case of the target pursuing ends guided missiles

摘要

The present invention relates to an orientable an optical imaging system for generating an image of an object scene on an image resolving detector (18), in particular for seeking heads in the case of the target pursuing ends guided missiles, as a wide-angle optical system with a first system part (12), by means of which an intermediate image (40) of the object scene is generated and a second system part (14), by means of this intermediate image (40) on the detector (18) can be imaged. The object of the invention is to provide a seeker head with a hemispherical detector (18) to build up in such a way that a large detection range with high resolution can be detected with a small window a large field of view and in that it can be detected with low inertia of a moving object scene in the field of vision, for example, a tracked target, is able to follow. According to the present invention, the first system part (12) of the imaging system (10) an intermediate image (20) of the field of view is generated. This intermediate image (20) also contains the object scene to be observed. The second system part (14) generates an image of a part (40) of this extended intermediate image (20) on the image resolving detector (18), for example, a matrix detector having a two-dimensional arrangement of detector elements. The detector (18), it is then merely necessary for this part (40) of the intermediate image (20) to dissolve in pixels, not the entire intermediate image (20). This results in a high resolution for the part of the ..
