TL;DR: In this article, a few-mode elliptical-core sensor was used to detect the amplitude and direction of dynamic strain in a graphite-epoxy composite. Butler et al. used a single-mode ECC fiber as the lead-in fiber and an offset circular-core singlemode fiber as lead-out fiber.

TL;DR: A self-referencing technique compensating for fiber losses and source fluctuations in reflective air-gap intensity-based optical fiber sensors is described, and the sensor is shown to be insensitive to both fiber-bending losses and variations in source power.

TL;DR: In this article, an intrinsic fiber-optic sensor is described which utilizes the surface plasmon effect to monitor the chemical environment surrounding the fiber, which is constructed by polishing a short section of the lateral surface of a single-mode fiber to within the evanescent field surrounding the core.

TL;DR: In this paper, a novel technique for effective detection of edge-induced and local internal delamination caused by cyclic loading of composite materials is proposed by employing the highly sensitive extrinsic Fabry-Perot interferometric optical fiber-based sensor for detecting discontinuities along the composite transverse axis.

TL;DR: In this article, a surface acoustic wave (SAW) sensor based on an extrinsic Fabry-Perot interferometer is described, where a singlemode fiber is used as the input/output fiber, and a multimode fiber, used solely as a reflector, form an air-gap that acts as a low-finesse Fabryperot cavity.
