  1. 1. Design and engineering of light-driven dynamic films for bioelectronic interfacing

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Luca Terenzi; [2023]
    Nyckelord :Conductive polymers; Stimuli responsive materials; Azopolymers; Cell-chip coupling; Bioelectronics; Konduktiva polymerer; Stimuli-känsliga material; Azopolymerer; Cell-chip-koppling; Bioelektronik;

    Sammanfattning : In the realm of neuroelectronics, the challenge lies in achieving finer observations of physiological processes to comprehend neuronal interactions and computations. This necessitates the development of more compliant and biomimetic interfaces for improved integration with biological tissues, enabling finer physiological process observations. LÄS MER

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

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

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

    Sammanfattning : 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. Implementation of adaptive optics into a femtosecond laser chain

    Master-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Sandhra-Mirella Valdma; [2015]
    Nyckelord :wavefornt correction; deformable mirror; femtosecond laser; wavefront sensor; shack-hartmann; adaptive optics; Physics and Astronomy;

    Sammanfattning : Optical aberrations are the main cause for reduced focusability and low peak intensity in laser beams. All the applications that rely on high peak power and/or small focus spot size, loose efficiency when optical aberrations are present. LÄS MER

  5. 4. Modeling and Control of a 1.45 m deformable mirror

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Pontus Giselsson; [2006]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The eagerness among astronomers to gain deeper knowledge and further understanding of the universe around us sets requirements for future telescopes.Images of more distant stars with higher spatial resolution is desired. Extremely Large Telescopes (ELTs) are being developed for this purpose. LÄS MER

  7. 5. Modeling and Control of a Large Deformable Mirror

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Fredrik Bjöörn; Olof Garpinger; [2005]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The current generation of earth-based telescopes has been of great use to astronomers for the past decades. New fields of astrophysics like the search for and analysis of earth-like planets would however need telescopes with even better resolution. LÄS MER
