Can fiber Bragg gratings be used to measure deflection
In this work, we present and discuss on the deflection estimation of a bi-dimensional panel by using Fiber Bragg Gratings (FBGs) as strain sensors embedded in the structure and a method based on the classical beam theory. A fiber Bragg grating is a small length of optical fiber that comprises a pattern of many reflection points that creates a reflection of particular wavelengths of incident light.

Theoretical Analysis of Fiber Bragg Gratings
This paper describes design, theoretical analysis, and experimental evaluation of a π-Phase-Shifted Fiber Bragg Grating (π-PSFBG) inscribed in the standard telecom fiber for slow light generation. At first, the grating was designed for its use in the reflection mode with a central wavelength of. in electronic engineering from the Pontifícia Universidade Católica of Rio de Janeiro in 1975 and a M. The crucial attenuation limit of 20 dB/km was first achieved in 1970 by researchers at Corning Glass Works (an American glass maker, now Corning Incorporated).

Intelligent Planar Waveguide
Optical planar waveguide sensors, able to detect and process information from the environment in a fast, cost-effective, and remote fashion, are of great interest currently in different application areas including security, metrology, automotive, aerospace, consumer. Traditionally, high-performance communication systems were based on rectangular waveguides (RWGs) to guide high-frequency signals. Newer, efficient RWG-like systems are now available with the added value of low cost, low volume and low weight, together with compactness and ease of manufacture. However, the existing DONNs based on free-space diffractive optical elements are bulky and unsteady. FIMMPROP is probably the most widely used propagation tool for the modelling of silicon photonics: rigorous (no slowly varying approximation), fully vectorial, offering wide angle capability and very high design flexibility. Integrated optical waveguide systems have emerged as foundational components for next-generation sensing technologies, owing to their exceptional miniaturization, high integration density, and compatibility with scalable planar fabrication.
