摘要： The invention relates to a module for an angle measuring device, comprising a dividing disc (1.3) made of a first material having a first longitudinal expansion coefficient (a1.3) and a carrier element (1.4, 1.4') made of a second material having a second longitudinal expansion coefficient (a1.4). The difference between the second longitudinal expansion coefficient (a1.4) and the first longitudinal coefficient (a1.3) is at least 3-10-6-K-1. The dividing disc (1.3) is attached to the carrier element (1.4, 1.4') by means of an adhesive bond, wherein the adhesive bond comprises an axial adhesive layer (1.1, 1.1') and a radial adhesive layer (1.2). The axial adhesive layer (1.1, 1.1') and the radial adhesive layer (1.2) disposed in an axial gap (Sa, Sa') and radial gap (Sr) respectively, each between the carrier element (1.4, 1.4') and the dividing disc (1.3). The two adhesive layers (1.1, 1.2) comprise different adhesives. The invention further relates to an angle measuring device having said module.

摘要： PROBLEM TO BE SOLVED: To provide a high resolution optical position measuring apparatus less susceptible to inclination of a scanning detection unit relative to a reference scale body with measuring scales around an axis perpendicular to a measuring scale face.SOLUTION: Luminous flux emitted from a light source 21 hits a measuring scale 11 and is here divided into at least two spectroscopic light fluxes. A spectroscopic light flux advancing in the direction of a scanning detection unit 20 hits a reflector element 25 via a first scanning detection scale 24, and is reflected in the direction of the measuring scale 11. At this time, the spectroscopic light flux passes through the first scanning detection scale 24 in a route toward the measuring scale 11. After hitting the measuring scale 11 again, the spectroscopic light flux is overlapped with the spectroscopic light flux advancing in the direction of a scanning detection unit 20, and is directionally converted into the direction of a detection unit 26 via a spectrometer element 22. Then, a plurality of scanning detection signals related to positions and having phases shifted to each other can be detected.

摘要： PROBLEM TO BE SOLVED: To provide an optical position measuring device having two intersecting reference scales and capable of adding a scanning distance between the two reference scales to execute measurement.SOLUTION: The scanning bar is extending in a first or a second direction of two directions X and Y while a scale is extending in the other direction and is offset from the scanning bar by a scanning distance d in a third direction Z perpendicular to the first and the second directions. The divice has a light source LQ, whose light passes through the scanning bar A at an intersection of the scanning bar A and scale M, falls on the scale M, and returns toward the scanning bar A to reach a detector. At the detector, the light is divided into different partial beams by diffraction at optically effective structures of the scanning bar A and the scale M and combined again. A periodic signal is obtained in the detector in response to a shift between the scanning bar A and scale M in the first direction X due to interference of combined partial beams, and a change in the scanning distance d between the scanning bar A and scale M.

摘要： PROBLEM TO BE SOLVED: To make a deflection unit for turning a light beam to a measurement reflector direction simple and compact.SOLUTION: A light deflection unit 40 includes a cardan structure including two cardan frames 41, 42, the first cardan frame 41 can be dynamically displaced around a first rotary axis A1 and the second cardan frame 42 existing on the inside of the first cardan frame 41 can be dynamically displaced around a second rotary axis A2 turned from the first rotary axis A1 at right angles. The two rotary axes A1, A2 intersect with each other at a position-fixed reference point R on which a reference reflector 30 is arranged. Since many mirrors are fixedly arranged on the cardan frames, a light beam through the plurality of mirrors can be turned around the position-fixed reference point R when directing the light beam to a measurement reflector.

摘要： PROBLEM TO BE SOLVED: To provide an optical position measuring apparatus which generates scan detection signals to which polarization coding is performed and whose phases are shifted, and is constituted as simply as possible.SOLUTION: The present invention relates to an optical position measuring apparatus for detecting a relative position between a reference scale and a scan detection plate which are movably arranged to be mutually relative along at lest one measuring direction. A light flux emitted from a light source is divided into at least two spectroscopic light fluxes for orienting polarization states at a right angle between each other by a first lattice. The spectroscopic light fluxes are integrated again to become one synthetic light flux, and a plurality of scan detection signals relevant to movement are generated in a detection unit from the synthetic light flux. Polarization means is arranged on light paths of the spectroscopic light fluxes, a polarization action of the polarization means to the spectroscopic light fluxes to be made incident on the light paths is periodically updated by using a polarization period along a degree of freedom of a motion of the reference scale, and the polarization period of the polarization means at the time is larger than a scale period of the first lattice.

摘要： An optical position-measuring device for detecting the position of two objects movable relative to each other in at least one measuring direction includes a measuring standard which is joined to one of the two objects and possesses an incremental graduation extending in the measuring direction, as well as at least one reference marking at a reference position. The reference marking includes two reference-marking subfields disposed in mirror symmetry with respect to a reference-marking axis of symmetry, each of the subfields being made up of a structure extending in the measuring direction and having a locally changeable graduation period. In addition, the position-measuring device has a scanning unit which is joined to the other of the two objects and to which a scanning device is assigned that is used to generate at least one reference signal at the reference position. The scanning device includes at least one light source emitting divergently in the direction of the measuring standard, as well as a detector system having elements which are disposed along the measuring direction such that, starting from a central detector-system axis of symmetry in the measuring direction, the center-to-center distances between adjacent elements in the same direction change like the graduation periods of the structures in the reference-marking subfields starting from the reference-marking axis of symmetry.

摘要： PROBLEM TO BE SOLVED: To minimize an error caused by eccentricity, in position measurement of two mutually-rotating objects. SOLUTION: In this position measuring device, detection devices 3.3, 3.4 acquire position information on a radial direction movement and a tangential direction movement by scanning two tracks 2.3, 2.4 having periodical grid scales rotating around an actual rotation axis. The detected position information is supplied to a calculation unit 4 through an interpolation unit 7, and a correction value K is calculated from an acquired signal, and stored in a memory unit 5 together with a corresponding position signal. In a normal position measuring operation, the calculation unit 4 reads out the correction value K corresponding to the position signal on reference to the memory unit 5, and corrects the position signal. Hereby, an eccentricity error can be reduced. COPYRIGHT: (C)2010,JPO&INPIT
