ABSTRACT:
The invention relates to a method for the contactless measurement of an object in at least one dimension. An object is scanned in a spatially restricted effective zone of a scanning beam field and the size of the object in terms of the measured dimension is deduced by the detection of one or more interruptions in the scanning beams. The scanning beam field is constructed from a number of directly addressable individual beams. The beam-assisted scanning of the spatially restricted effective zone of the scanning beam field is carried out according to a predefinable pattern of steps, using a non-linear soiling method.
