Abstract: A system and a method for generating three-dimensional image displays with two sensors, in particular two thermal imagers, having two optical channels with fields of view of equal size and with a virtually identical line of sight has at least one image reproduction unit. The optical axes of the sensors are aligned in parallel with one another. The sensors are each provided with a detector for a stereo recording, the stereo recording being performed simultaneously by means of the detectors.

Abstract: A panoramic viewing apparatus has an imaging system that is arranged in a housing provided with a rotary drive. The imaging system has a lens system by means of which the images of the objects are imaged on a detector after passing through the lens system. There is provided in the beam path for the purpose of compensating the image motion caused by the rotation a counter-motion device that produces during the imaging time a motion directed at least approximately synchronously against the rotation produced by the rotary drive. The counter-motion device is arranged in a convergent beam path of the lens system.

Abstract: A zoom lens comprises in a direction of light propagation a front lens group (G1) having positive refractive power, a variator lens group (G2) having negative refractive power, a compensator lens group (G3) having positive refractive power, and a base lens group (G4) having positive refractive power. The base lens group (G4) comprises a first base lens group (G4.1) and a second base lens group (G4.2). The front lens group (G1), the variator lens group (G2), the compensator lens group (G3) and the first base lens group (G4.1) are arranged along a common straight first optical axis (23). The second base lens group (G4.2) is arranged along a second optical axis 23?) inclined with respect to the first optical axis (23) at a first angle ? different from 0° and 180°. A beam deflector (18) is arranged between the first base lens group (G4.1) and the second base lens group (G4.2).

Abstract: The invention relates to a scanner, wherein a position of a moveable part of the scanner is adjusted by inputting a command variable which changes repeatedly in the same manner. A command signal corresponding to the command variable is supplied to a controller (3), the controller (3) being constructed for correcting a setpoint deviation in the presence of a command variable which is constant in time. A control error of the controller (3) which arises from the change in the command variable is corrected by evaluating a setpoint deviation of the position of the moveable part or an equivalent variable, obtaining from this a correction signal and changing an output signal of the controller (3) by using the correction signal.

Abstract: The invention relates to a multichannel receiver system (1) for angularly resolved laser ranging measurement, in which a laser light pulse from a laser (7) using the pulse travel time method is used to measure the ranges of a plurality of target points (6) by means of an array (2) comprising a plurality of apertures (3), of a photodetector (9) and of an evaluation circuit (10). The laser light pulses entering each of the apertures (3) and reflected by the target points (6) are distributed in a preselected distribution ratio between at least two optical fibers (511 to 543) with an individual length which corresponds to a light travel time tn,m, and are subsequently received by the photodetector (9) and are processed in the evaluation circuit (10). A unique assignment of the pulses to the respective apertures (3) is rendered possible by their spacings, specified in accordance with the distribution, and amplitudes. The ranges of the target points (6) can thereby be determined.

Abstract: Radiation receiver with a photodetector and a sensor, wherein the sensor receives the radiation intensity, and a shutter arranged before the photodetector is driven in dependence on the detected incident radiation intensity. The incident radiation is supplied to the photodetector via a delay device arranged before the shutter, so that no radiation destroying the photodetector can reach the photodetector, due to the shutter having been driven, and can if necessary be kept away or absorbed by the shutter.

Abstract: The invention is directed to a directionally adjustable telescope arrangement (1) having a first arcuate mirror (3), a second arcuate mirror (9) and a planar deflecting mirror (13). A third arcuate mirror (17) is provided in the imaging beam path of the telescope arrangement (1). The mirror (17) coacts with the first arcuate mirror (3) and the second arcuate mirror (9) to effectively form images.

Abstract: A camera has camera optics and an optics support (3) which is rotatably journalled in a camera housing (5) and includes the camera optics. The camera optics include a first pivot mirror (7) at the input end and a second pivot mirror (11). The first pivot mirror (7) is pivotable about a first pivot axis (9) relative to the optics support (3). The optics support (3) is rotatable relative to the camera housing (5) about a rotational axis (9) parallel to a first pivot axis (9). Furthermore, the second pivot mirror (11) can be pivoted about a second pivot axis (13) running transversely relative to the first pivot axis (9).
