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.

Method for evaluating Fresnel diffraction border profiles

Method for measuring the cross-sectional dimension of an elongated profile having rounded or sharp edges, in particular of a flat or sector cable by illuminating the article with light sources and determination of a plurality of shadow borders and calculating the parameter of the circle from the coordinates of the light sources and the shadow borders. The dimensions are determined from the circular parameter.

Method for measuring the dimension of a non-circular cross-section of an elongated article in particular of a flat cable or a sector cable

A method for measuring the diameter of an elongated article approximately circular in cross section, in particular of a wire or of a cable, which may include some or all of the following:
