摘要： A laser source is used in a geodesic device to improve the emission of laser light, in which the laser diodes emitting multimodal radiation are influenced by a mode-selective component such that the laser radiation emitted by the laser source has monomodal character. An edge emitter or a vertical semiconductor emitter with an external cavity, is hence used, in which a mode selective component is arranged, for example, a monomode fibre or resonator mirror, which has the effect of a mode-selective resonator construction. Components with negative dispersion can be used for pulse compression to compensate for the greater pulse duration generated by the lengthened cavity.

摘要： The aim of the invention is to determine the actual position and/or actual orientation of a measuring appliance (4b). To this end, at least two reference points (2b′) lying in a spatial segment (5′) scanned by a laser beam are detected and measured in terms of the distance thereinbetween and the inclination angle thereof. The actual position of the measuring appliance (4b) can be deduced from the known positions of said reference points (2b′) arranged in a detectable manner and the associated distances and inclination angle thereof. The detection, monitoring and measuring of the reference points is carried out by the measuring appliance (4b) in an automated manner, the measuring appliance (4b) and specifically embodied elements associated with the reference points (2b′) forming a local positioning and/or orientation measuring system. The inventive method and corresponding devices enable measurements to be carried out in a problem-free and automated manner, even in areas that cannot be accessed by other measuring systems.

摘要： An optoelectric angle-measuring device according to the invention has a code carrier having a position code (C1) which can be detected optically as well as a scanning device in the form of a light-sensitive row or area for detecting the position code (C1) and generating a position-dependent scanning signal. The scanning device which is in the form of a scanning film (F1), in particular, surrounds the code carrier or the code carrier essentially completely surrounds the scanning device along a circumference. This provides an extremely accurate angle-measuring device by virtue of the fact that a large part of the position code (C1), in particular even the entire position code (C1), can be detected.

摘要： In a method for correcting optical wavefront errors in an optical system, the optical wavefront is calculated for different wavelengths and fields of view between the entry pupil (EP) and exit pupil (AP). Any phase differences are compensated by at least one surface (5, 7) compensating the phase differences in the beam path. A particular optical system, expediently in the form of a telescope, accordingly has a beam path which comprises the following: a first reflector (3), arranged along its axis (A), for reflecting a beam (1) incident along an optical axis (O) onto a concave second reflector (4) which throws the beam obtained from the first reflector (3) onto a third reflector (5), from which it is passed to a concave fourth reflector (6) in order to be reflected at an angle with said optical axis (O). Such a means (5, 7) for correcting the wavefront errors is provided in the beam path of such an optical system. The axis (A) of the first reflector (3) can optionally make an angle (&agr;) of 0° with the optical axis (O); the means (5, 7) permits the correction of asymmetry errors resulting from the angular position.

摘要： The description relates to the measurement of the inclination of boundary areas in an optical system and a device for implementing the process. Starting with an auto-collimation process which determines the inclination of this boundary area in relation to a reference axis from the deviation of a light beam collimated onto the boundary area to be investigated and reflected on a position-sensitive photodetection system, a twin-beam interferometer process with downstream evaluation electronics is provided which permits the separation of the interferogram, intensity-modulated according to the invention, of the boundary area to be investigated from the unmodulated disturbance reflections of those not to be investigated as far as the interferogram intensities in the photon-noise range and thus offers a resolution in the deviation of the center of gravity of the interferogram of the order of 10 nm. To modulate the intensity of the interferogram, the difference in the optical distance between the reference and test beams to the boundary area to be investigated is time-modulated.

摘要： The invention relates to an optoelectronic angle sensor (1a) for determining a rotational angle about an axis (6), comprising a circular disk (2a) that can be rotated about the axis. Said circular disk comprises a coding, essentially over the entire surface, a flat photosensitive detector (3a), a device for producing an evaluable image of the coding on the detector and a memory and evaluation component (4a) for determining the rotational angle. A largely complete, or in particular an entire image of the coding is produced on the detector. The rotational angle is determined using a parameter-varying stochastic comparison method, from the image and a parameterised electronic reference pattern that is provided by means of the memory and evaluation component.
