  1. 1. Remote sensing phenology at European northern latitudes - From ground spectral towers to satellites

    University dissertation from Department of Physical Geography and Ecosystem Science, Lund University

    Author : Hongxiao Jin; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Remote sensing; climate sensitivity.; calibration; ground spectral tower; Plant phenology index PPI ; northern latitude;

    Abstract : Plant phenology exerts major influences on carbon, water, and energy exchanges between atmosphere and ecosystems, provides feedbacks to climate, and affects ecosystem functioning and services. Great efforts have been spent in studying plant phenology over the past decades, but there are still large uncertainties and disputations in phenology estimation, trends, and its climate sensitivities.

  2. 2. Colorimetric and Multispectral Image Acquisition

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Daniel Nyström; Linköpings universitet.; Linköpings universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Color imaging; Multispectral imaging; Spectral reconstruction; Device characterization; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik Bildanalys;

    Abstract : The trichromatic principle of representing color has for a long time been dominating in color imaging. The reason is the trichromatic nature of human color vision, but as the characteristics of typical color imaging devices are different from those of human eyes, there is a need to go beyond the trichromatic approach.

  3. 3. Fourier transform and Vernier spectroscopy using optical frequency combs

    University dissertation from Umeå : Umeå University

    Author : Amir Khodabakhsh; Umeå universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; optical frequency comb spectroscopy; molecular absorption; resonant cavity; Fourier transform spectroscopy; Vernier spectroscopy; fysik; Physics;

    Abstract : Optical frequency comb spectroscopy (OFCS) combines two previously exclusive features, i.e., wide optical bandwidth and high spectral resolution, enabling precise measurements of entire molecular bands and simultaneous monitoring of multiple gas species in a short measurement time.

  4. 4. Sampling visual space: topography, colour vision and visually guided predator avoidance in fiddler crabs (Uca vomeris)

    University dissertation from Research School of Biological Sciences, The Australian National University

    Author : Jochen Smolka; [2009]

    Abstract : Many animals use vision to guide their behaviour and to collect relevant information about their environment. The diversity of visual environments and of visually guided tasks has led to a large variety of specialisations of eyes and visual systems. READ MORE

  5. 5. Phosphor Thermometry on Surfaces - A Study of its Methodology and its Practical Applications

    University dissertation from Research School of Biological Sciences, The Australian National University

    Author : Christoph Knappe; Lund University.; Lunds universitet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coating Thickness; Temperature Calibration; Two-Colour Ratio; Lifetime Decay; Thermometry; Thermographic Phosphor; Laser Combustion Diagnostics; Laser-Induced Phosphorescence; Non-Linearity; ICCD; PMT; Signal Processing Algorithms; Fysicumarkivet A:2013:Knappe;

    Abstract : Phosphor Thermometry is a term describing an optical measurement technique for remote temperature sensing. Its working principle is based on the temperature-sensitive emission characteristics of certain ceramic substances termed thermographic phosphors. READ MORE
