1. Experimental Adaptive Optics. A test facility for adaptive optics on a small telescope
Sammanfattning : This thesis presents the work on the design of, construction of, and finally observations with, an experimental setup comprising a small telescope equipped with adaptive optics. The facility has been assembled at Lund Observatory, where also observations on the sky have been made. LÄS MER
2. Wavefront Aberrations and Peripheral Vision
Sammanfattning : Failing eyesight causes a dramatic change in life. The aim of this project is to help people with large central visual field loss to better utilize their remaining vision. Central visual field loss means that the person has to rely on peripheral vision since the direct vision is lost, often due to a dysfunctional macula. LÄS MER
3. Spatial and temporal aspects of intense attosecond pulses for pump-probe experiments
Sammanfattning : Nuclear and electronic dynamics in atoms and molecules are the foundation of many physical processes and chemical reactions. Often, these dynamics take place on timescales so much shorter than those commonly encountered that they are called ultrafast. LÄS MER
4. Extremely Large Telescopes Optical Design and Wavefront Correction
Sammanfattning : An overview of the state of art within optical design of large astronomical telescopes is given. Recent advances within the field are presented. The importance of new computer-controlled mirror-polishing methods is emphasized. LÄS MER
5. Phase diversity wavefront sensing and image restoration applied to high-resolution solar observations
Sammanfattning : .... LÄS MER
