  1. 1. Improving the experimental setup for ultrasound-optical tomography imaging

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ibtisam Dahir Ahmed; [2023]
    Nyckelord :Ultrasound-optical tomography UOT ; thulium-doped lithium niobate;

    Sammanfattning : According to Bröstcancer förbundet, mammography is not efficient at detecting tumors in dense breast tissue or diagnosing breast cancer at its early stages. Ultrasound-optical tomography (UOT) is an imaging technique in development and has the potential for deep-tissue imaging. LÄS MER

  3. 2. Performance Estimation of a 1D pulsed LiDAR : A Study of SiPM-Based LiDAR in Ambient Light

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Joel Rune; [2023]
    Nyckelord :LiDAR; SiPM; SPAD; Ambient light; LiDAR; Kisel-fotomultiplikator; SPAD; Bakgrundsljus;

    Sammanfattning : LiDAR is a remote sensing technology that uses a laser to map the surrounding environment. With its many applications, for example in autonomous vehicles, LiDAR is a growing field within technology and research. The silicon photomultiplier (SiPM) is a solid state device commonly used in the receiving system of a LiDAR. LÄS MER

  4. 3. Fabrication of sub-10 nm solid-state nanopores by electrical breakdown

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Kasumi Tsutsumi; [2023]
    Nyckelord :Nanopore fabrication; Solid-state material; Silicon nitride; Graphene; DNA translocation; Nanopor-avkänning; fast tillståndsmaterial; kiselnitrid; grafen; DNA-translokation;

    Sammanfattning : Nanopore sensing is a versatile technique that employs very small openings, known as nanopores, to study biomolecules. The use of nanopores on solid-state membranes has gained attention due to its potential for low-cost and high-throughput sensing of single molecules in liquids. LÄS MER

  5. 4. Free-Space Dark Pulse Mode-Locked Laser

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Martin Brunzell; [2021]
    Nyckelord :Solid State Laser; Sum-frequency generation; Dark pulse; Mode-locked; Laser; Summa-frekvens generation; mörk puls; modlåst;

    Sammanfattning : While the development of bright pulses produced in free space devices can be found in a large set of applications and research equipment all over the world. The production of dark pulses in a free-space device has not been shown prior to this work. LÄS MER

  7. 5. Faster Environment Modelling and Integration into Virtual Reality Simulations

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Jonas Nyman; [2021]
    Nyckelord :3D re-construction; Digital Photogrammetry; LiDAR; Remote Sensing; Point Cloud; Point cloud to mesh; Terrestrial Laser Scanning; Static Laser scan; Virtual Reality;

    Sammanfattning : The use of virtual reality in engineering tasks, such as in virtual commissioning, has increased steadily in recent years, where a robot, machine or object of interest can be simulated and visualized. Yet, for a more immerse experience, an environment for the object in question needs to be constructed. LÄS MER
