  1. 1. Environmental Monitoring by Multi-Spectral Lidar Techniques

    University dissertation from Department of Physics, Lund University

    Author : Petter Weibring; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; non-linear optics; fluorescence spectroscopy; scattering; multi-spectral imaging; Atom- och molekylärfysik; atmospheric pollution; Atomic and molecular physics; laser; remote sensing; lidar; DIAL; Fysicumarkivet A:2002:Weibring;

    Abstract : 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. READ MORE

  2. 2. Development of laser spectroscopy for scattering media applications

    University dissertation from Department of Physics, Lund University

    Author : Mats Andersson; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laserteknik; Laser technology; Atom- och molekylärfysik; Atomic and molecular physics; Fysik; Physics; coherent sampling; optical sensor; light absorption; noninvasive measurement; diode laser; scattering of light; laser spectroscopy; fluorescence spectroscopy; remote sensing; Lidar; DIAL;

    Abstract : 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. READ MORE

  3. 3. Laser Remote Sensing for Environmental Monitoring

    University dissertation from Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Author : Zuguang Guan; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fiber-optic sensor; gas analysis; food-package monitoring; multiple scattering; zero-background measurement; diode laser spectroscopy; ecological study; aerosol; trace pollutant; LIDAR; laser-induced fluorescence; DIAL; methane monitoring;

    Abstract : 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. READ MORE

  4. 4. Development and Application of Single-Ended Picosecond Laser Diagnostics

    University dissertation from Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Author : Billy Kaldvee; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Raman Scattering; Temporal Filtering; Picosecond Laser Diagnostics; Rayleigh Scattering; Laser-spectroscopy; DIAL; Laser Combustion Diagnostics; Lidar; Laser-induced Fluorescence; Laser-induced Incandescence; Fysicumarkivet A:2012:Kaldvee;

    Abstract : 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. 5. Modeling and Simulation of Dial-a-Ride and Integrated Public Transport Services

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Carl Henrik Häll; Linköpings universitet.; Linköpings universitet.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dial-a-ride; simulation; optimization; modeling; paratransit; public transport; TECHNOLOGY Other technology; TEKNIKVETENSKAP Övriga teknikvetenskaper;

    Abstract : Traditional public transport systems are most often insufficient to provide a good transport service to everyone. Especially, it is not always possible for elderly and disabled persons to use the regular system consisting of timetabled services operating along fixed routes. READ MORE
