    Abstract: A method for determining a refractive index in a surface region of an object from a production system which has not cooled to an ambient temperature includes emitting terahertz radiation from a transmitter at an angle of incidence to the surface region of the object. The terahertz radiation is reflected from the surface region of the object and received by a receiver. The refractive index of the surface region of the object from a ratio of the emitted and reflected terahertz radiation is determined using an evaluator in communication with the transmitter and the receiver. The influence of surface properties of the object on a portion of the reflected terahertz radiation is taken into account when determining the refractive index.

    Abstract: A device for performing a measurement of a strand-shaped object comprises at least one transmission apparatus configured to emit measuring radiation onto the strand-shaped object, which reflects the measuring radiation. At least one receiving apparatus is configured to receive the measuring radiation reflected by the strand-shaped object. An evaluation apparatus is configured to determine at least one of (1) the diameter and (2) the outer contour of the strand-shaped object based on the measuring radiation received by the at least one receiving apparatus. At least one retroreflector is configured to surround at least a portion of the strand-shaped object and retroreflect at least some of the measuring radiation reflected by the strand-shaped object.

    Abstract: A method for contactlessly determining the temperature of a moving object having an unknown degree of emission, especially a metal wire conveyed along its longitudinal axis, is described: The object is guided through at least one radiation source emitting thermal radiation, wherein the object is mostly or completely surrounded by the at least one radiation source. With at least one radiation detector, a spatially-resolved thermal radiation measurement is performed in a region through which the object passes when it is guided through the radiation source. The temperature of the moving object is determined on the basis of the spatially-resolved thermal radiation measurement. A corresponding device is also described.

    Abstract: A method for determining the position of at least one edge of an object, in particular a strand, comprises illuminating the object using light from at least one coherent light source, wherein diffraction borders are generated on both geometric boundaries of the shadow caused by the object. The method also includes recording the spatial intensity profile of at least one diffraction border using at least one single or multi line optical sensor, differentiating the at least one recorded intensity profile with respect to location and plotting it using a squared location axis, and comparing the at least one recorded intensity profile, differentiated with respect to location and plotted using a squared location axis, to at least one periodic reference intensity profile. The position of at least one edge of the object is determined on the basis of the completed comparison.
