1. Methods of Multi-Conjugate Adaptive Optics for Astronomy
Abstract : This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future.

2. Designer magnetoplasmonics for adaptive nano-optics
Abstract : Materials that provide real-time control of the fundamental properties of light at visible and near-infrared frequencies enable the essential components for future optical devices. Metal nanostructures that couple electromagnetic (EM) radiation on a sub-wavelength length scale to free electrons, forming propagating or localized surface plasmons, provide many exciting functionalities due to their ability to manipulate light via the local EM field shaping and enhancement.

3. Experimental Adaptive Optics. A test facility for adaptive optics on a small telescope
Abstract : 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. READ MORE

4. Peripheral Vision : Adaptive Optics and Psychophysics
Abstract : This thesis is about our peripheral vision. Peripheral vision is poor compared to central vision, due to both neural and optical factors. The optical factors include astigmatism, defocus and higher order aberrations consisting mainly of coma. Neurally, the density of ganglion cells decreases towards the periphery, which limits the sampling density. READ MORE

5. Adaptive Optics in Integrated Modeling of Telescopes
Abstract : This thesis present the implementation of a modular adaptive optics (AO) model, as part of an integrated model of extremely large telescopes (ELTs). The purpose of the project has been to establish knowledge within integrated modeling, with emphasis on adaptive optics. READ MORE
