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.
Abstract:
An apparatus (2) and a method for producing a representation of an object scene, including a detector arrangement (12) with a plurality of detector units (20, 22) and an optical unit (4, 8) for producing the image of the object scene on the detector arrangement (12). To produce a high information content from representations of the object scene the apparatus (2) includes a filter unit (16, 26, 32, 72) arranged in an imaging beam path, with a first radiation filter raster with a first filter property and at least one second radiation filter raster with a second filter property different from the first filter property, wherein the radiation filter rasters penetrate each other, and a motion unit (100) for stepwise movement of an image of the radiation filter rasters relative to the detector arrangement (12).
Abstract:
A wide-angle optical system (2, 40) having an objective (4, 42) and a mirror system, including a curved mirror (6, 46) for projecting a wide-angle image through the objective (4, 42) onto a detector (10, 44). At least one mirror (8, 46) of the mirror system is arranged movably relative to the objective (4, 42). It is possible to achieve a zoom function, a large elevation range and a selection of an enlarged section from the wide-angle image.
