摘要:
An imaging device (2) for the stabilized imaging of an object onto a detector (14) with a first optical unit (4) and a second optical unit (6) and an optical element that is arranged between the optical units (4, 6) and can be moved for the purpose of stabilizing the imaging on the detector (14). For image stabilization in order to compensate for an undesirable wobbling movement of the imaging over the detector (14), the optical element is constituted of a micro-optical lens array (10).

An optical arrangement (2) for a homing head (16), for the purpose of imaging an object scene onto a detector unit (4), including a control unit (24), a first optical unit (10) having two at least partially transparent optical elements, in particular prisms (42, 44), a second optical unit (14) and a beam deflecting unit (18), the first optical unit (10) directing radiation from at least two sections of the object scene onto the beam deflecting unit (18) in a superimposed fashion, and the beam deflecting unit (18) selecting one of the sections and, in conjunction with the second optical unit (14), imaging the selected section on the detector unit (4).
摘要:
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).
摘要:
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.
摘要:
A camera system (2, 40, 50) including a sensor (12, 58) and a first optical system which includes a convex mirror (4, 42) and through which the image of a solid angle region (14) is producible on the sensor (12, 58) by way of a first beam path (18). In order, in addition to producing an image of a large solid angle region (14), to permit scanning or detailed representation of a smaller partial region (20, 66, 82) of the solid angle region (14), the camera system (2, 40, 50) includes a second optical system through which a partial region (20, 66, 82) of the solid angle region (14) is detectable by way of a second beam path (34, 60) on a detail sensor (68), wherein the detail region (20, 66, 82) is selectable by an optical element (28) which is movable relative to the sensors (12, 58, 68).
摘要:
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.
摘要:
An object detection system has an image detection system with an imaging detector, a position detection system with a position detector, and optics which guide incident radiation onto both detectors. The two detectors are arranged one behind the other, in particular adjacent to one another, in the beam path. This makes it possible to achieve a simple, compact and reliable object detection system.
摘要:
An image sensor system includes a detector having a plurality of detector elements and optics having a beam path from an optical element on to the detector. Calibration of the detector can be rapidly effected where the image sensor system has a reference radiating device fixed within the beam path for illuminating the detector elements.
摘要:
An image of a surrounding area is projected onto a detector of a detector device by way of an optical system that produces an imaging beam path. A screen is disposed in the imaging beam path and the screen shadows a subarea of the image of the surrounding area on the detector. In order to allow an object which is dazzling the detector device to be masked out and nevertheless to allow the surrounding area to be monitored, the screen is subdivided into a plurality of segments which can be operated individually, and segments which are associated with the subarea are selected and operated, and are in this way heated. The transmission of the selected segments is reduced by the heating throughout the frequency range in which the detector is sensitive, and the selected segments of the screen thus shadow the subarea of the image.
摘要:
An apparatus for swiveling an optical beam has a swiveling unit with a number of micro-optical grids for swiveling the beam. In order to compensate for beam errors, such as wavefront aberrations or diffraction effects, the apparatus includes an adaptive optical device with a phase shifter for correction of beam errors in the beam.
