    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Felix Fritzén; [2023]
    Keywords : FBG force sensor; Fiber Bragg Grating force sensing; Fiber optic force sensor; Optical force sensing; Strain-based force sensing; Bragg wavelength shift; Force measurement using FBG; Fiber optic sensing technology; Fiber optic grating sensor;

    Abstract : The purpose of this project is to explore the FBG (Fiber Bragg Grating) technology and create a force sensor. The result can be used as a basis for further projects.The project starts with force and strain measurements. The project then evolves to incorporate multiple FBG sensors. READ MORE

  3. 2. Practical Trials of Fiber Optical Gyroscope Based Inertial Navigation System

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Tim Djärf; [2023]
    Keywords : Technology and Engineering;

    Abstract : There exists a need for inertial navigation systems within a multitude of applications, such as drones, unmanned vehicles, and guidance systems. Saab produces gyroscopes for stabilization purposes, but the gyroscopes could also be used as part of an inertial navigation system. READ MORE

  4. 3. Development of a validation shape sensing algorithm in Python with predictive and automatedanalysis

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Carlos Castellanos; [2021]
    Keywords : python; FBG; deflection; wavelength; machine learning; forecast;

    Abstract : Difficulties with wind turbines can arise during operation due to externalforces provoked by the wind. Calculating the deflection of the blades can beused to give break points for maintenance, design and/or monitoring purposes. READ MORE

  5. 4. Distributed Temperature Sensing Using Phase-Sensitive Optical Time Domain Reflectometry

    University essay from KTH/Tillämpad fysik

    Author : Simon Ek; [2020]
    Keywords : Applied physics; Distributed optical fiber sensing; Rayleigh scattering; OTDR; phase-OTDR; Temperature; Refractive index; Strain; Correlation; RISE; Single mode fiber; SMF; Tillämpad fysik; Distribuerad optisk fibermätning; Rayleigh-spridning; OTDR; phase-OTDR; Temperatur; Brytningsindex; Töjning; RISE; Korrelation; Singelmodfiber; SMF;

    Abstract : This thesis explores and evaluates the temperature measuring capabilities of a phase-sensitive optical time-domain reflectometer (φ-OTDR), which exploits Rayleigh backscattering in normal single mode optical fibers. The device is constructed and its setup explained, and a protocol for making temperature measurements with it is developed. READ MORE

  6. 5. Optical Fiber sensing of acoustic waves using overlapping FBGs

    University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

    Author : Erik Lillebø Hole; [2019]
    Keywords : Ultrasonic; Optical Fiber Sensing; Fiber Bragg Grating;

    Abstract : The objective of this thesis was to investigate if an optical fiber sensing method with the use of two overlapping fiber Bragg gratings to measure Lamb wave $S_0$ modes in a steel plate, and how it would compare to traditional PZT transducers. A solution was proposed where the use of an optical fiber sensing system was built and took advantage of the strain dependence of a fiber Bragg grating mounted to a steel plate. READ MORE
