  1. 1. Calibration and evaluation of the secondary sensors for the Mini-EUSO space instrument

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Jonah Ekelund; [2018]
    Nyckelord :Mini-EUSO; EUSO; calibration; evaluation; near-infrared light; visible light; camera; phosphorus coating;

    Sammanfattning : The Mini-EUSO (Mini - Extreme Universe Space Observatory) is an instrument for observation of ultra-high energy cosmic rays (UHECR) from space. It is designed to observe Earth from the international space station (ISS) in the ultra-violet (UV), visible (VIS) and near-infrared (NIR) light ranges. LÄS MER

  2. 2. Studies on Radiation-induced Defects in InP/InAsP Nanowire-based Quantum Disc-in wire Photodetectors

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Ebrahim Mansouri; [2018]
    Nyckelord :InP InAsP; QDiscs-in-wire; photodetectors; proton irradiation; Photocurrent; I-V characteristics;

    Sammanfattning : Photodetectors are used in many applications such as digital and thermal cameras or in solar panels. They can also be designed to detect the omnipresent high-energy radiation/particles, and for radiation imaging in biomedical applications. LÄS MER

  3. 3. Unbiasing entomological kHz Scheimpflug LIDAR data

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

    Författare :Alexandra Andersson; [2018]
    Nyckelord :Entomological LIDAR; Insect detection; Wing-beat frequency; Unbiasing of analysis model; Physics and Astronomy;

    Sammanfattning : Insects can be mapped using a method called Scheimpflug Lidar (LIght Detection And Ranging). Sending out light in the near infrared range and detecting the backscattered echo, it is possible to resolve flying organisms in range and time. Insect observations can be distinguished from the background signal through adaptive thresholding. LÄS MER

  4. 4. Design of a metal detector

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Ammar Haider; [2018]
    Nyckelord :Antenna; Radar; Frequency;

    Sammanfattning : Electromagnetic wave propagation is a well-known phenomenon in the scientific world and when the first telescope was built method of sensing objects excelled afterwords. Research in optical system and infrared is growing day by day but radar system still dominates the world in object sensing. LÄS MER

  5. 5. Short-Wave Infrared Lidar on Atmospheric Aerosols and Insects

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

    Författare :Mariam Andersson; [2017]
    Nyckelord :Lidar; Scheimpflug; Time-of-Flight; Remote sensing; Atmospheric sensing; Physics and Astronomy;

    Sammanfattning : This thesis focusses on the implementation of two elastic lidar (light detection and ranging) techniques for the monitoring of atmospheric aerosols and insects at short-wave infrared wavelengths. Data acquisition software was developed for a time-of-flight system, housed in the Lund University Mobile Biosphere Observatory (LUMBO), with consideration to the intended entomological application.
