  1. 1. Enhancement of a Power Line Information System by Combining BIM and LiDAR Data

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Author : Daniel Wollberg; [2024]
    Keywords : GIS; BIM; FME; CloudCompare; GIS; BIM; FME; CloudCompare;

    Abstract : With the great ongoing energy transition in Sweden, Svenska Kraftnät (SVK) sees a huge need for investment in the Swedish transmission network and supporting IT- systems.  SVK has a great amount of collected laser data over the electric power transmission network however this data does not contain any semantic attribution that can be analyzed on broader information systems.

  3. 2. Focal Spot Optimization Using Spatial Light Modulation and a Phase Retrieval Algorithm

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

    Author : Robert Petersen; [2023]
    Keywords : Spatial Light Modulation; Phase Retrieval Algorithm; Focal Spot Optimization; Adaptive Optics; Wavefront Sensing; Lasers; Physics and Astronomy; Technology and Engineering;

    Abstract : Aberrations to the wavefront of a laser beam reduce the quality of the focal spot and are generally undesired. This project is aimed at determining the aberrations of laser beams by using a phase retrieval algorithm and to show that it is possible to correct the aberrations with a spatial light modulator to optimize the focal spot.

  4. 3. Product-development for laser powder bed fusion

    University essay from KTH/Produktionsutveckling

    Author : Ludvig Dagberg; David Hu; [2023]
    Keywords : Laser Powder Bed Fusion; Additive Manufacturing; DFAM; Selective Laser Melting; Design for Additive Manufacturing; Laser beam fusion;

    Abstract : This thesis investigates the differences in the design process when developing a product for additive manufacturing (AM) compared to traditional manufacturing methods, such as CNC machining. In recent years, additive manufacturing (AM), including metal-based laser powder bed fusion (L-PBF), has gained popularity, leading to increased adoption by companies. READ MORE

  5. 4. ADDITIVE MANUFACTURING OF PURE COPPER USING ELECTRON BEAM MELTING (EBM)

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Prithiv Kumar Chinnappan; Vishal Shanmugam; [2022]
    Keywords : Additive Manufacturing; Electron Beam Melting; Pure Copper; Process Optimisation.; Additiv tillverkning; Elektronstrålesmältning; Ren koppar; Processoptimering.;

    Abstract : Pure copper (Cu) has the properties of high optical reflectivity and surface tarnishing as well as excellent thermal and electrical conductivity. Accordingly, laser-based additive manufacturing (AM) techniques confront various difficulties to produce thismaterial. READ MORE

  6. 5. Investigation of a New Method for Drone Dazzling Using Laser

    University essay from Linköpings universitet/Reglerteknik

    Author : Jens Grundmark; [2021]
    Keywords : Drone countermeasure; Risley prisms; Camera dazzling; Laser;

    Abstract : Drones have become more common, and are commercially available for consumers. Small drones can be used for unauthorized information gathering, or to cause disruptions. This has created a need for safe, effective countermeasures against drones. In this thesis, a method for countermeasures against drone imaging is investigated. READ MORE
