11. Optical Detection Using Computer Screen Photo-assisted Techniques and Ellipsometry
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
12. Multi-level modulation formats for high-speed optical transmission systems
Sammanfattning : Over the past several years, the use of multi-level modulation formats has enabledsignificant improvements in the field of optical fiber communication, particularlyin terms of per-channel bit-rate (i.e., line-rate) and spectral efficiency (SE), byencoding multiple bits per symbol.

13. Optical Mapping of Bacterial Plasmids
Sammanfattning : Bacteria that have acquired resistance to antibiotics represent one of the largest threats to human health and modern health care. The genes encoding resistance are frequently spread via the transfer of plasmids, which are circular double stranded DNA molecules separate from the chromosomal DNA of the bacteria. LÄS MER
14. Optical Diagnostic Techniques Applied in Practical Combustion Devices and Processes
Sammanfattning : Optical measurement techniques have proven to be useful tools for studying combustion-related phenomenon. The fact that the techniques are optical facilitates performing the measurements without impinging upon the measurement object, such as the combustion event that can be involved. LÄS MER
15. Optical Imaging for Nanowire Mechanics
Sammanfattning : In this work, we present a stroboscopic detection technique for the study of oscillating nanoscale objects. This optical read-out gives a position accuracy better than 1 nm which is a fraction of both the diffraction limit and the pixel size. LÄS MER
