  1. 1. Multi-spectral X-ray imaging with a laser-plasma accelerator

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Andrea Angella; [2022]
    Keywords : Multi-spectral imaging; single-photon counting; X-ray absorption spectroscopy; XAS; LWFA; laser-wakefield acceleration; K-edge; imaging; metal-detection algorithm; Physics and Astronomy;

    Abstract : This master thesis focuses on the creation of an algorithm to perform multispectral imaging of a metallic target using X-rays. The generation of an ultrashort high-power low-divergent X-ray beam is performed by means of a Ti:Sapphire laser driven wake-field plasma accelerator. READ MORE

  3. 2. Analysis of atmospheric influences on ratio thermography for solar tower systems

    University essay from Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Author : Albin Englin; [2022]
    Keywords : Concentrated solar power; Ratio thermography; Shortwave infrared; Gray body assumption; Atmospheric compensation;

    Abstract : The knowledge of temperature and emissivity of the receiver are both critical for a solar tower power plant, in order to guarantee an efficient operation of the thermal receiver on the one hand, while monitoring any degradation of the receiver coating on the other hand. To make these measurements, a new thermographic system is currently being developed, using a multispectral camera working in the short wavelength infrared spectrum. READ MORE

  4. 3. Assessment of Drone-Borne Multispectral Mapping in the Exploration of Magmatic Ni-Cu Sulphides – an Example from Disko Island, West Greenland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Ethan Barnes; [2020]
    Keywords : mineral exploration; UAV; multispectral sensors; Illukunnguaq dyke; Greenland;

    Abstract : The senseFly eBeePlus fixed-wing drone is a market available UAV compatible with a range of sensors that includes the Parrot Sequoia+ multispectral camera. Commercial applications of the drone predominantly focus on agriculture, environmental management, and engineering applications. READ MORE

  5. 4. RGB and Multispectral UAV image classification of agricultural fields using a machine learning algorithm

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Sigurbjörn Jónsson; [2019]
    Keywords : Physical Geography and Ecosystem Analysis; UAV; classification; Random Forest; Geomatics; segmentation; Earth and Environmental Sciences;

    Abstract : A common technique within image analysis is image classification which describes the process of reducing the information content of an image into few user-defined classes. With the emergence of unmanned aerial vehicles (UAVs), high spatial resolution (cm-level) images can be collected. READ MORE

  6. 5. Direct multispectral photogrammetry for UAV-based snow depth measurements

    University essay from KTH/Geoinformatik

    Author : Kathrin Maier; [2019]
    Keywords : Unmanned Aerial Vehicles UAV ; snow depth; direct photogrammetry; multispectral imagery; cryosphere;

    Abstract : Due to the changing climate and inherent atypically occurring meteorological events in the Arctic regions, more accurate snow quality predictions are needed in order to support the Sámi reindeer herding communities in northern Sweden that struggle to adapt to the rapidly changing Arctic climate. Spatial snow depth distribution is a crucial parameter not only to assess snow quality but also for multiple environmental research and social land use purposes. READ MORE
