摘要： An arrangement as well as a method for the automatic correction of error-containing scanning signals, which contain defined deviations from the ideal signal shape, of incremental position measuring devices is disclosed, wherein an ideal signal shape is presupposed by a downstream arranged evaluation unit. In this case the scanning signals are supplied to a processor unit, and correcting values are determined by means of a correction algorithm which are converted in turn into appropriate control signals. The analog scanning signals as well as the control signals are supplied to a correction unit, which contains several adjustment possibilities for correcting the error-containing scanning signals by the control signals acting on them. The processor unit as well as the correction unit are arranged in such a way that scanning signals, which have already passed through the correction unit, are present at the input side of the processor unit.

摘要： An error correction system for correcting machine errors or division errors in a position measuring instrument for precision machines is disclosed. The system is usable, for example, in conjunction with instruments for measuring the relative position of two objects, wherein an incremental grid division formed on a measuring scale is scanned by a scanning unit to generate analog measurement signals. According to this invention, the scale defines additional correction tracks which extend along the scale, parallel to the division, and are scanned by additional scanning elements included in the scanning unit. These additional scanning elements operate to generate analog correction signals from the correction track. These analog correction signals are used to correct the analog measurement signals with respect to errors such as amplitude errors, phase angle errors, and zero crossing errors.

摘要： The angular graduation of a graduated disk is scanned in a measuring device by a scanning unit by the movement of light beams in two angular graduation areas located diametrically opposite each other. To compensate for wobble errors caused by the wobbling of the graduated disk, the light beam emanating from a light source impinges on the graduated disk at a point outside of the angular graduation and, following reflection and deflection by a triple prism, impinges parallel to itself in the form of a light beam on an impact point in a first the graduation area. The light beam is split into two diffraction beams by the graduation, and meet, after having passed through a deflection prism, at a meeting point in a second angular graduation area. Since the impact point and the meeting point are always located on the same radius, the wobbling of the disk does not have a disadvantageous effect on the accuracy of measurement.

摘要： A process and apparatus for obtaining harmonic-free periodic signals in an incremental measuring system is disclosed in which a graduation having a graduation period P is scanned by at least six scanning elements (for the case in which the previously determined bandwidth N of the analog signals obtained in scanning the graduation N is equal to 3). The periodic analog signals generated by the scanning elements are subjected to a Fourier analysis for the determination of the Fourier coefficients of the base or fundamental wave of the periodic analog signals. These Fourier coefficients are then evaluated as harmonic-free periodic signals for the formation of position measuring values.

摘要： A position measuring system that includes a scale graduation and a scanning element, wherein the scanning element moves relative to the scale graduation along a measurement direction so as to generate position-dependent, intensity-modulated output signals. The scanning element includes a dynamic characteristic, which has saturation areas adjoining both sides of an at least partially approximately linear operating area, in which no significantly changed output signal results any more, even when the input signal changes. The scanning gap (d) between the scale graduation and the scanning element is selected in such a way that as the scanning element moves over its entire measurement range a modulation between maximum input signals, which are located in the saturation areas of the dynamic characteristic, takes place. In order to eliminate the distortions of the output signals which usually occur in this modulation area it is furthermore provided to perform signal filtering in order to remove, in particular, the third harmonic from the output signal.
