  1. 1. Multiple Fibre Bragg Grating Force Sensor

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Felix Fritzén; [2023]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Gas Emissions from Contaminated Fibrous Sediments in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Fredrik Collin; [2020]
    Nyckelord :Fiberbank; fibrous sediment; gas ebullition; GHG emissions; methanogenesis; optical ebullition sensor; Fiberbank; fibersediment; gas ebullition; växthusgas emissioner; metanogenes; optiska ebullitions sensore;

    Sammanfattning : Gas Emissions from Contaminated Fibrous Sediments in Sweden The discharge of untreated wastewater from pulp and paper mills have resulted in the accumulation offibrous sediments on the bottom of many nearby aquatic recipients. Some accumulations are multiplemeters thick and consist almost entirely of cellulose fibre or wood chips; these are called fiberbanks. LÄS MER

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Jonathan Le Guillarme; Jakob Lindstam; [2019]
    Nyckelord :Structural Health Monitoring; Bridge Maintenance; Monitoring With Sensor Technology; Fibre Optical Sensors; Acoustic Emission; Bridge Constructions; Concrete Damages; Damage Mechanisms; Structural Health Monitoring; Tillståndsbedömning; Övervakning med sensorteknik; Fiberoptiska sensorer; Akustisk emission; Brokonstruktioner; Betongskador; Skademekanismer;

    Sammanfattning : Sverige har som många länder runt om i världen en åldrande infrastruktur och behovet av underhåll stiger. I en artikel i Svenska Dagbladet från 21/9–2018 redovisar analys- och teknikkonsultföretaget WSP en grov uppskattning att 300 miljarder kronor behöver investeras för att rusta upp existerande infrastruktur.

  5. 4. Optronic enclosure for a Naval application.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Felicia Nordberg; [2019]
    Nyckelord :;

    Sammanfattning : This Master thesis is a collaboration with Saab Järfälla with the purpose to find a more protective cover for the electro-optical side of their fire control director CEROS 200 version CWI. The project started with a background research to find as much information about the director as possible and examining some competitors within the area. LÄS MER

  7. 5. Designing an Experiment to Investigate Slow Light Effects in Whispering Gallery Mode Resonators

    Master-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Karolina Dorozynska; [2015]
    Nyckelord :Slow light; Whispering Gallery Mode Resonator; WGMR; Atomic physics; Physics and Astronomy;

    Sammanfattning : Slow light and Whispering Gallery Mode Resonators are two interesting and useful fields with applications in optical sensing and laser stabilisation among others. Slow light can lead to long interaction times which are useful in light-matter interactions such as sensitive non-linear optics. LÄS MER
