1. 1. Prospects for a Free Electron Laser at the FemtoMAX Beamline

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

   Author : Johan Holmberg; [2024]
   Keywords : Free Electron Lasers; FEL; synchrotron radiation; MAX IV; FemtoMAX; GENESIS 1.3; XFEL; X-rays; soft X-rays; Physics and Astronomy;

   Abstract : A Free Electron Laser (FEL), is a device that generates extremely coherent and brilliant radiation using electrons accelerated to relativistic velocities in a particle accelerator. The process utilises similar equipment to what is used at a synchrotron source like MAX IV, but in addition there is an interaction between the relativistic electron beam and the generated radiation to achieve an exponential growth in radiation intensity.

3. 2. Laser dazzling of CMOS imaging sensors using amplitude modulated and continuous wave lasers

   University essay from Umeå universitet/Institutionen för fysik

   Author : Johan Fjellström; [2023]
   Keywords : ;

   Abstract : Protecting sensitive information is important, especially in defence applications. As cameras become more common, developing countermeasure systems that limit the information gathering capabilities of imaging sensors would be beneficial. READ MORE

4. 3. Comparative Analysis of Spatiotemporal Playback Manipulation : Evaluating Desktop Environments versus Immersive Head-Mounted Virtual Reality Environments

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Andreas Wrife; [2023]
   Keywords : virtual reality; surgical simulations; external ventricular drainage; motion capture; interaction controls; virtuell verklighet; kirurgiska simuleringar; extern ventrikeldränage; motion capture; interaktionskontroller;

   Abstract : Virtual Reality (VR) is a creative tool that enables immersive learning, planning and training of surgical operations. Extensive research has been conducted in multiple surgical specialities where VR has been utilized, such as spinal neurosurgery. However, cranial neurosurgery remains relatively unexplored in this regard. READ MORE

5. 4. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

   Abstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

6. 5. Quantification and Detection of Motion Artifacts in Laser Speckle Contrast Imaging

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Dennis Amphan; [2022]
   Keywords : Laser speckle contrast imaging; Image registration; Motion artifacts; Detection;

   Abstract : Laser speckle contrast imaging (LSCI) is a non-invasive method for assessment of microcirculatory blood flow. The technique is based on analysis of speckle patterns to build 2D maps of perfusion with high spatial and temporal resolution. READ MORE
