摘要： A position-measuring device is for determining the position of two objects which are arranged displaceably with respect to each other in at least one measuring direction, and a method is for the operation of such a position-measuring device. The position-measuring device includes a measuring graduation as well as a scanning device having a light source and one or a plurality of optical and/or optoelectronic components for generating displacement-dependent position signals. A semiconductor laser having great coherence length is provided as the light source, which is operated pulsed in a single-mode operational-mode.

摘要： A position-measuring system is for measuring the position of an object, movable in several degrees of freedom, relative to a stationary object. The position-measuring system includes at least one measuring graduation that is joined to one of the objects, as well as a plurality of scanning units which are joined to the other object and which generate raw position signals based on the optical scanning of the measuring graduation. Moreover, a multiplexer unit is provided, the raw position signals generated by the scanning units being supplied to the multiplexer unit, and from there, the raw position signals of the various scanning units being transmitted in time multiplex operation to a downstream sequential electronics, without converting the raw position signals into position values beforehand.

摘要： A position-measuring device, for ascertaining the position of two objects which are disposed in a manner allowing movement relative to each other in at least one measuring direction, includes a light source, as well as a splitting device by which a light beam, provided by the light source, is split into two or more partial beams of rays. The partial beams of rays traverse at least two partial-beam paths. Interfering partial beams of rays from the partial-beam paths strike a plurality of opto-electronic detector elements, so that displacement-dependent position signals are ascertainable via the detector elements. The light source takes the form of a semiconductor laser having a fiber-grating feedback device.
