FREMGANGSMAADE OG APPARAT TIL OVERVAAGNING AF DIAMETEREN AF FIBRE

摘要

A method and apparatus for monitoring the average diameter of a plurality of glass fibers, comprising illuminating the fibers with electromagnetic radiation, sensing radiation scattered by the fibers and generating a signal responsive to the amount of radiation sensed as an indication of the average diameter of the fibers; such signal can be used for measurement and/or control of the fiber producing process.
