摘要：device for non-contact measurement of a distance from a surface (11), inparticular for scanning a surface of a workpiece along a contour of a me\ßweges,with a me\ßk\örper (1) in which an optoelectronic device is arrangedthe light onthe measured surface (11) by means of the throw surface reflected light of the distancefrom the surface er\­zeugt dependent signal. the me\ßk\örper (1) is inme\ßrichtung movements of a tripod (4).the optoelectronic device has a

fokuslagenme\ßsystem and an optoelectronic lageabtast\­einrichtung (8) forscanning the position of the me\ßk\örpers (1) with respect to the tripod (4).awith a display or schreibeinrichtung associated adder adds the electrical output signal ofthe fokuslagenme\ßsystems the electric output signal from the

lage\­abtasteinrichtung added, thus forming a summensignal, the distance of themeasured surface in me\ßk\örpers any bewegungslage of

me\ßk\örpers (1) of the tripod (4).the measured value is composed of twoteilwerten additive composition, and the fokuslagenme\ßsystem gelie\­ferte

fraction tr\ägheitsfrei is formed, while the other fraction of a large section andallows, for example, the measurement of a grobprofils allowed.
