摘要： A displacement measuring system for measuring relative displacements between two members. The second member is free to move relative to the first member along a main guide. The first member has a scale element which tracks the main guide. The second member is coupled to a scanner which moves along its own guide (which may be constituted by the scale element itself) scanning the scale element to provide a measure of the relative displacement. The coupling is flexible in directions at right angles to the direction of relative displacement in order to compensate for tracking errors between the main guide and the scale.An embodiment in which the scale is located off the neutral axis of the scale element the coupling is flexible in a first plane on the level of the neutral axis and in a second plane which includes the longitudinal central axis of the scale and is at right angles to the first plane.

摘要： A length measuring system having a scale with a first portion and a second portion separated by a gap, wherein the first and second portions each have incremental graduations. The system further includes a scanner unit for scanning the incremental graduations of the first and second portions, wherein the scanner unit has two groups of scanner elements spaced apart by a greater than the width of the gap. The system has at least one control track parallel to and next to the incremental graduations of the first and second portions. A further scanner element is provided to scan the at least one control track and produce an output signal, wherein the output signal is a function of the absolute position of the first and second portions and controls a switchover from one group of scanner elements to the other group of scanner elements. The absolute position of the first and second portions is derived from the control track over the entire measurement length of the scale and the measurement increment of the control track is greater than the measurement increment of the incremental graduations of the first and second portions.

摘要： An angle measuring device which includes a graduated disc and a stator is mounted to an external drive unit which includes a drive shaft and an attachment surface. The graduated disc is fixedly mounted to the drive shaft such that it is the drive shaft which guides the movement of the disc. The stator is mounted directly to the attachment surface such that the stator does not guide the movement of the graduated disc. In order to align the stator properly with respect to the drive shaft and the graduated disc, a centering collar is provided on the attachment surface, concentric with the drive shaft. The centering collar interacts with at least two alignment surfaces defined by the stator. These alignment surfaces are positioned to define the desired orientation of the stator with respect to the drive shaft.

摘要： A distance measuring instrument comprising a source of coherent light and a receiver is disclosed which may be used to measure the one dimensional position of an object surface. Coherent light is directed at a predetermined angle onto the object surface and the angle at which diffusely reflected light from this surface enters the receiver is measured. This entrance angle is measured with a photosensor and a movable aperture formed by the intersection of a fixedly mounted diaphragm and a movably mounted diaphragm. By measuring the position of the movably mounted diaphragm when the movable aperture is placed so as to allow reflected light to pass from the illuminated surface to the photosensor, the entrance angle of the reflected light and hence the position of the object is determined.

摘要： A position measuring device for measuring the relative position of two objects (01, 02) comprising a graduation (Ta) in a graduation plane (TFa) of the graduation carrier (TTa) which is connected to one of the objects (01). The object (01) is scanned by a scanning unit (A) which is connected to the other object (02) by means of a carrier (MT). Between the carrier (MT) and the scanning unit (A), a coupling link (K), preferably in the form of a leaf spring, is aligned in the direction of measurement X. This spring has only one rotational degree of freedom in a direction perpendicular to the graduation surface (TFa) of the graduation carrier (TTa). A guide mechanism (F) comprises a guide element (FE) which guides the scanning unit (A) in a direction parallel to the direction of measurement X on a guide surface (FFa) of the graduation carrier (TTa). The guide surface (FFa) is perpendicular to the graduation surface (TFa) of the graduation carrier (TTa). The guide mechanism (F) further comprises a guide joint (FG) for connecting the scanning unit (A) with the guide element (FE). The guide joint (FG) possesses at least one translational degree of freedom perpendicular to the direction of measurement X.
