Abstract:

This paper proposes a noninstrumental computer method for monitoring the twist of a thread, using a program for Fourier processing micro-images of the surface of a digital micro-image of the test thread. This program can first be used to calculate the diffraction pattern from a micro-image, after which the same program can calculate a second diffraction pattern from that calculated initially. An algorithm is proposed for processing this pattern in order to output the twist of the test thread. It is illustrated that this method can be applied to model samples and samples of commercial synthetic threads.
