Yarn diameter measurements using coherent optical signal processing

A method to measure variations in yarn diameter using coherent optical signal processing based on a single photodiode plus additional electronics is described. The approach enables us to quantify yarn irregularities associated with diameter variations which are Iinearly correlated with yarn mass var...
