Abstract: In an image resolving detector arrangement, an image of an object scene is generated by an imaging optical system. Radiation from a respective one of several adjacent image elements of an image area associated with the detector element is directed consecutively onto each of the detector elements by an image element selection device. Herein the image element selection device is formed by a micro-light stop raster, which is arranged in an image plane and moveable step by step in this image plane, and which, in each position, allows only radiation from a part of an image area associated to a detector element to pass onto the detector element. Thereby, the resolution of the image resolving detector arrangement is improved.
