摘要： The effectiveness of a method for checking for exact alignment of two successive shafts, axles or the like is improved by the fact the no measures with respect to linearization or temperature compensation are necessary any longer by using a light-sensitive array as the light-sensitive sensor. The effects of outside light and reflections can be suppressed. The cross section and the quality of a detected laser beam can be checked especially by visual inspection. Production of the corresponding device for executing this process is facilitated. By using matched beam splitters and reflectors as well as light sources of different colors the number of optoelectronic sensors necessary can be significantly reduced.

摘要： The spatial position of rollers or other mutually adjacent articles is measured or examined by indirect transport of a reference direction. To this end, an adaptor is placed on one of the rollers. The adaptor is equipped with a light source which emits a light beam substantially parallel to the axis of rotation of a roller. The light beam is sensed by a movable sensor unit. The latter determines, at the same time, the angle of incidence of the light beam according to two axes, relative to the sensor unit, and the orientation of the sensor unit relative to a reference axis system (laboratory system). A multi-axially operating gyroscope is used for the last-mentioned measurement. A suitably programmed electronic system or computer determines, from the two measured values, the orientation of the adaptor and of the roller with respect to azimuth and elevation in the laboratory system. The measured values which are determined can be utilized for the purpose of making a comparison with the corresponding values of further rollers or articles, so that an apparatus for parallelism measurements which is easy to handle is provided.

摘要： The shock protection device prevents damage to optically and micromechanically acting gyroscopes. The gyroscope or precision instrument to be protected can be located in an inner housing shell which is spaced apart from an outer housing shell by elastic elements, and is thereby protected against shock. The inner housing shell can be brought temporarily into accurate mechanical contact with the outer housing shell by an electromechanical device. The spatial orientations of the inner and outer housing shells then correspond with high precision. In a further embodiment of the invention, the electromechanical device can be used precisely conversely to deactivate an existing shock protection and temporarily to bring about direct contact between a sensing element and an object to be checked on the occasion of a measuring operation.

摘要： Method for nondestructive and contact-free detection of faults in a test specimen which is moved relative to a probe that detects a periodic electrical signal having a carrier oscillation whose amplitude and/or phase is/are modulated by any fault in the test specimen. The probe signal is filtered and sampled by a triggerablie A/D converter stage to obtain a demodulated digital measurement signal which is filtered using a digital frequency-selective adjustable second filter unit to obtain a useful signal which is evaluated to detect a fault in the test specimen. The A/D converter stage is triggered at a fraction of the frequency of the carrier oscillation selected as a function of the fault frequency obtained as the quotient of the relative speed between the test specimen and the probe and the effective width of the probe, and the frequency-selective second filter unit is adjusted as a function of the fault frequency.

摘要： An optical position-measuring device includes a measuring standard and a scanning unit. The measuring standard includes an incremental graduation and at least one reference marking at a reference position. The reference marking has two reference-marking subfields disposed in mirror symmetry relative to a reference-marking axis of symmetry, each of the subfields including a grating structure having a locally changeable graduation period. The scanning unit includes a divergently emitting light source, one or more gratings, and a reference-signal detector system. The reference-signal detector system has at least four detector arrays formed and positioned such that, from the scanning of the reference marking via the reference-signal detector system, first and second pairs of partial reference signals result, in each case having a signal pattern in phase opposition. The first pair of partial reference signals is offset by an offset amount relative to the second pair of partial reference signals.

摘要： An optical position-measuring device includes a scanning bar extending in a first or second direction, and a scale extending in the other direction. The scale is offset by a scanning distance from the scanning bar in a third direction perpendicular to the first and second directions. The device has a light source whose light penetrates the scanning bar at an intersection point of the scanning bar and scale to fall on the scale and arrive back at the scanning bar. At a detector, the light is split by diffraction into different partial beams at optically effective structures of the scanning bar and scale and combined again. A periodic signal is obtained in the detector in response to: a shift between the scanning bar and scale in the first direction due to interference of combined partial beams, and a change in the scanning distance between the scanning bar and scale.
