  1. 1. 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

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Daniel Álvarez Franco; [2022]
    Nyckelord :Geant4; scintillation; BGO; CsI; simulation; COSI; telescope; photoelectric effect;

    Sammanfattning : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources. LÄS MER

  4. 3. Achieving Optimal Alignments of IR Source and Detector in Waveguide Based Gas Sensor

    Uppsats för yrkesexamina på grundnivå, KTH/Medicinteknik och hälsosystem

    Författare :Sefik Güler; Agbai Randolph Agwu; [2020]
    Nyckelord :Non-dispersive infrared technology; microelectromechanical systems; infrared light; electromagnetic spectrum; gas sensor; light emitting diode; photodiode detector; Icke-dispersiv infraröd teknologi; mikroelektromekaniska system; infrarött ljus; elektromagnetiskt spektrum; gassensor; lysdiod; fotodioddetektor;

    Sammanfattning : I takt med att tekniken för mikroelektromekaniska system utvecklas uppkommer det nya områden för tillämpning. Ett område är inom gassensorer där icke-dispersiv infraröd strålning används genom att mäta absorptionen hos olika gaser för att bestämma mängden av en specifik gas i luften. LÄS MER

  5. 4. Polymer Assisted Transfer of Graphene onto Semiconductor Substrates

    Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Synkrotronljusfysik

    Författare :Jonathan Frisby; [2020]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Since first being isolated in 2004, Graphene has been researched heavily because of its unique properties. Recently, interest has grown in graphene/semiconductor heterostructures. In this work, the transfer of graphene through the use of cellulose acetate butyrate (CAB) polymer is studied. LÄS MER

  7. 5. Optical communication with underwater snake robots : Design and implementation of an underwater wireless optical communication system

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Jaime Marco Rider; [2019]
    Nyckelord :optical communications; underwater wireless; robot communications;

    Sammanfattning : Eelume AS is a norwegian company that develops autonomous underwater vehicles. Their flagship model is an underwater snake robot that performs inspection, maintenance and repair operations. For the time being, Eelume has been using acoustic communications between their AUV's and the docking station, but it has a big drawback: bandwidth. LÄS MER
