  1. 1. Multiple Fibre Bragg Grating Force Sensor

    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. Simulation, Design, and Implementation of a Narrow Linewidth Ytterbium Fiber MOPA System at 1087 nm

    University essay from KTH/Tillämpad fysik

    Author : Berkay Efilti; [2023]
    Keywords : Applied Physics; Laser Physics; Fiber Lasers; Fiber Amplifiers;

    Abstract : This thesis focuses on simulating, designing, and characterizing a narrow-linewidth continuous-wave (CW) Ytterbium (Yb) master oscillator fiber amplifier (MOFA) system. The primary goal was to achieve a watt-level output at 1087 nm with a narrow 1 GHz linewidth, making the MOFA well-suited for serving as a pump source in Terahertz (THz) generation experiments.

  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. Evaluation of Strain and Temperature Measurements with Fiber Bragg Grating for Loss Verification and Heat Transfer of Ball Bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Alexander Karlsson; Eric Marcus; [2021]
    Keywords : fiber bragg grating; bearings; temperature; strain; heat transfer; bearing losses; measurements;

    Abstract : Volvo Cars is in a change of producing only electric and hybrid cars by 2025.Subcomponent testing is a crucial part to ensure the quality of the individual buildingblocks in an electric machine. Any way of making these tests more reliable and less timeconsuming is of great interest at Volvo. READ MORE

  6. 5. Transmission characterization of fiber Bragg gratings arrays for intracavity spectral control of a 1.5 micrometer fiber laser

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Hu Leo Qiyuan; Pontus Jäderholm; [2021]
    Keywords : ;

    Abstract : This thesis aims to investigate whether a fiber Bragg grating array (FBGA) can be designed to reduce the bandwidth of light from a 1.5 µm fiber laser while the distances between the fiber Bragg gratings are in the 10-20 cm range. READ MORE
