Fiber Bragg Grating Wavelength Demodulation Methods

A wavelength demodulation method for ultra-short fiber Bragg grating (US-FBG) sensors based on an arrayed waveguide grating (AWG) and a convex optimization algorithm is proposed and demonstrated. In this paper, a novel demodulation algorithm based on the variable-step-size method and cross-correlation algorithm is proposed to demodulate the wavelength of an FBG. Instead of measuring the output power ratio of the two adjacent AWG channels as previously done, in. The aim of this article is to introduce an innovative algorithm for the calculation of the shift of the maximum reflectivity wavelength of a Fiber Bragg Grating experiencing an applied strain.

Methods of melt fiber coiling

Melt spinning is used for polymers that can be melted easily. In this process, a viscous melt of polymer is extruded through a spinneret containing a number of holes into a chamber, where a blast of cold air or gas is directed on the surface of fibers emanating from the. Within a spectrum of fabrication techniques, melt-spinning has emerged as an eco-friendly and scalable method for making fibers from biodegradable plastics (preferably bio-based), intended for various applications. This paper provides a comprehensive overview of the advancements in the realm of. This review introduces the key principles and parameters that influence the performance of melt electrowriting and explores the current mathematical modelling under four stages: (1) heating and extrusion system, (2) formation of the Taylor cone, (3) formation and injection of the melt jet, and (4). Polymer fibers are central to countless applications, from textiles and composites to filtration and biomedical materials. Their performance is largely determined not only by the polymer used, but also by the way the fibers are processed.
