1. Environmental Monitoring by Multi-Spectral Lidar Techniques
Sammanfattning : Multi-spectral lidar (light detection and ranging) techniques have been developed and employed in various environmental studies, ranging from concentration mapping of volcanic emissions to fluorescence imaging of historical monuments. In both absorption measurements of gaseous species and fluorescence imaging of stones, multiple wavelength excitation and multiple wavelength detection have been applied. LÄS MER
2. Development of laser spectroscopy for scattering media applications
Sammanfattning : Laser spectroscopy for both large and small spatial scales has been developed and used in various applications ranging from remote monitoring of atmospheric mercury in Spain to investigation of oxygen contents in wood, human sinuses, fruit, and pharmaceutical solids. Historically, the lidar group in Lund has performed many differential absorption lidar (DIAL) measurements with a mobile lidar system that was first described in 1987. LÄS MER
3. Laser Remote Sensing for Environmental Monitoring
Sammanfattning : This thesis studies the techniques of laser remote sensing and their applications in environmental monitoring, as documented in several published papers. The environment where the human being live is degrading with an accelerating speed. LÄS MER
4. Development and Application of Single-Ended Picosecond Laser Diagnostics
Sammanfattning : Light detection and ranging (lidar), a method for nonintrusive, single-ended, and range resolved measurements, has been developed and applied for combustion related diagnostics. Employing picosecond laser pulse durations and detectors providing temporal resolution on the order of picoseconds, lidar has been applied successfully for both quantitative temperature- and species concentration measurements, obtaining an ultimate range resolution of 0.

5. Diode-laser absorption spectroscopy - applications in medicine and environmental monitoring
Sammanfattning : A major part of this thesis work has been research in a medical project, where, together with industry and clinical partners, the aim was to develop a prototype system for non-invasive monitoring of premature babies based on the optical measurement technique gas in scattering media absorption spectroscopy (GASMAS). Part of the project was to develop a 3D-printed tissue phantom based on chest X-ray images of the thorax of a premature infant. LÄS MER
