Abstract
In the method for detecting a periodic structure in a moving elongated textile material, the textile material is scanned simultaneously at several detection points which are arranged in an equidistant manner along its longitudinal direction. Scanning signals detected at the detection points are added to form a composite signal. As a result of temporal changes in the composite signal, conclusions are drawn on the periodic structure of the textile material. A spatial spectrum of the structure of the textile material can be obtained practically without any computational effort in several groups of several respective equidistant detection points.

A method for detecting a periodic structure in a moving elongated textile material, comprising:
- simultaneously scanning the textile material at several discrete detection points arranged along its longitudinal direction and spaced in an equidistant manner from each other,
- adding scanning signals detected at the detection points to form a composite signal, and
- identifying temporal changes in the composite signal as indicative of a periodic structure of the textile material.
A device for detecting a periodic structure in a moving elongated textile material, comprising:
- a substrate comprising
- several discrete detection points, which are arranged along the longitudinal direction of the textile material and are spaced from each other in an equidistant manner, for the simultaneous optical scanning of the textile material, and
- an optical waveguide structure integrated on the substrate for merging light fractions detected at the detection points and for guiding the merged light fractions to a outcoupling interface, which is arranged for outcoupling light from the waveguide structure.
