11. Morphological and Physiological Adaptations in Cichlid Crystalline Lenses
Abstract : Vertebrate eyes share a common ancestry as well as the basic design with a pupil, a retina and a lens. The lens is essential for perceiving the details in the world around us and ensures that a sharp image of the surroundings is focused onto the photoreceptors in the retina. READ MORE

12. Daylighting Systems : Development of Techniques for Optical Characterization and Performance Evaluation
Abstract : Successful integration of daylighting systems requires the ability to predict their performance for given climates. In this dissertation, a bottom-up approach is applied to evaluate the optical performance of a selection of daylighting systems. READ MORE

13. On optical methods for intracerebral measurements during stereotactic and functional neurosurgery : Experimental studies
Abstract : Radio frequency (RF) lesioning and deep brain stimulation (DBS) are the two prevailing surgical treatments for movement disorders within the field of stereotactic and functional neurosurgery. For RF-lesioning, a small volume of brain tissue is coagulated and knowledge of the lesion size and growth is of great importance for the safety and outcome of the procedure. READ MORE

14. Development of Models, Methods, and Materiel for Deep Tissue Imaging using Light, Ultrasound, and Spectral-Hole Burning
Abstract : The medical imaging technique called “ultrasound optical tomography” (UOT) entails light scattered in tissue that is given spatial information by interacting with an ultrasound field, thus allowing for molecular information to be imaged with ultrasonic resolution. This thesis discusses how UOT can be implemented, with most attention put toward the implementation using spectral-hole-burning filters (SHF) in rare-earth-ion-doped crystals. READ MORE

15. Dynamic and quasi-stationary electrochromic response of amorphous tungsten oxide thin films : In situ combined electrochemical and optical measurements during lithium intercalation
Abstract : Electrochromic (EC) materials can adjust their optical properties, reversibly, by means of an external electrical stimulus. They have relevant technological applications; for example, energy-efficient smart windows, which can adapt dynamically—according to the given environmental conditions—to control the heat and visible light fluxes between the interior and exterior of a building.
