TLDR
Recent research and applications in structural health monitoring of composite aircraft structures using FOS have been critically reviewed, considering both the multi-point and distributed sensing techniques.Abstract:
In-service structural health monitoring of composite aircraft structures plays a key role in the assessment of their performance and integrity. In recent years, Fibre Optic Sensors (FOS) have proved to be a potentially excellent technique for real-time in-situ monitoring of these structures due to their numerous advantages, such as immunity to electromagnetic interference, small size, light weight, durability, and high bandwidth, which allows a great number of sensors to operate in the same system, and the possibility to be integrated within the material. However, more effort is still needed to bring the technology to a fully mature readiness level. In this paper, recent research and applications in structural health monitoring of composite aircraft structures using FOS have been critically reviewed, considering both the multi-point and distributed sensing techniques.read more

Probing micron-scale distributed contortions via a twisted multicore optical fiber
TL;DR: In this article, the authors reported the first distributed measurements of fiber contortions with an ultrahigh sensitivity (≤0.3 μm in the transverse plane, 40 μm longitudinal spatial step size, and ≤8 μm resolution for periodic contortion in the longitudinal plane) via a Bragg-grating-inscribed twisted multicore optical fiber.

Skin–stringer debonding detection using distributed dispersion index features
TL;DR: This article proposes a preliminary investigation on the use of a non-model-based damage identification method, implementing “dispersion feature” indicators, extracted from the differential strain signal, based on data obtained as a consequence of point impacts on a wing box stiffened panel.
