1. 31. Complex Oxide Photonic Crystals

   Författare :Dzmitry Dzibrou; Alex Grishin; Peter Lazor; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Photonic crystals; magneto-optical effects; refractive index; iron garnet; Optics; Optik;

   Sammanfattning : Microphotonics has been offering a body of ideas to prospective applicationsin optics. Among those, the concept of photonic integrated circuits (PIC’s) has recently spurred a substantial excitement into the scientific community. Relisation of the PIC’s becomes feasible as the size shrinkage of the optical elements is accomplished. LÄS MER

3. 32. Wavefront Aberrations and Peripheral Vision

   Författare :Linda Lundström; Peter Unsbo; Austin Roorda; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optics; Human eye; Aberrations; Peripheral vision; Central visual field loss; Optics; Optik;

   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

4. 33. Femtosecond Dynamics of Dissociation and Isomerization Reactions in Solutions

   Författare :Jose-Luis Alvarez; Kemisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optics; Electromagnetism; Photochemistry; Fotokemi; acoustics; Elektromagnetism; optik; akustik; Fysicumarkivet A:1997:Alvarez;

   Sammanfattning : The main purpose of this work has been to investigate the fundamental dynamics of photodissociation and photo-induced isomerization reactions in the condensed phase. These "elementary" reactions have been chosen as model processes for exploring the influence of the solvent on a chemical event, as well as the factors that control this influence. LÄS MER

5. 34. Optical Detection Using Computer Screen Photo-assisted Techniques and Ellipsometry

   Författare :Jimmy W. P. Bakker; Hans Arwin; Jin Gang; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical sensing; Biohttps: www.diva-portal.org liu webform form.jsp#paper0sensing; Ellipsometry; Computer Screen Photo-assisted Technique; Fluorescence; Immunoassays; Optics; Optik;

   Sammanfattning : Two main subjects, ellipsometry and computer screen photo-assisted techniques (CSPT), form the main line in this thesis. Ellipsometry is an optical technique based on the detection of polarization changes of light upon interaction with a sample. LÄS MER

7. 35. New innovative methods for non-intrusive optical diagnostics of high-voltage insulator materials

   Författare :Magnus Bengtsson; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Atom- och molekylärfysik; Atomic and molecular physics; akustik; optik; optics; acoustics; Electromagnetism; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; fluorescence; optical diagnostics; high-voltage insulation; remote sensing; polymeric insulators; lidar; biological contamination; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Energy research; Energiforskning; Elektromagnetism;

   Sammanfattning : The purpose of this PhD thesis work has been to develop optical techniques that can help utility engineers for assessing the state of insulators in service and in a laboratory. The possibilities to use remote laser induced fluorescence for detection and imaging of biological growth such as algae and fungi have been investigated. LÄS MER
