    摘要: A position measuring system for determining the relative position of two objects includes a power supply unit for generating a variable operating current for a laser light source. At least one photodetector generates position-dependent output signals from the light received from the laser light source. In measurement operation, the power supply unit provides a direct current having a superimposed alternating current component to the laser light source.

    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 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.
