Analysis of The Norwegian Veterinary Institute's Model for Salmon Lice Abundance Prediction
Bogen, Johannes (Master thesis, 2018)Empirical studies have found that lice from salmon farms are a main source of infection of wild salmonids. Due to Norway s responsibility to conserve wild stocks of salmon, Veterinærinstituttet has created a statistical ... -
Modelling Underwater Hyperspectral Images
Sørensen, Tord Kriznik (Master thesis, 2017)The underwater hyperspectral imager is a new type of imager able to acquire hyperspectral images under water. Common consumer cameras have poor spectral resolution and only captures light in three bands, in the red, green ... -
Numerical Simulations of Scattering of Light from Two-Dimensional Rough Surfaces Using the Reduced Rayleigh Equation
Simonsen, Ingve; Nordam, Tor; Letnes, Paul Anton (Journal article; Peer reviewed, 2013)A formalism is introduced for the non-perturbative, purely numerical, solution of the reduced Rayleigh equation (RRE) for the scattering of light from two-dimensional penetrable rough surfaces. Implementation and performance ... -
Numerical studies of the transmission of light through a two-dimensional randomly rough interface
Hetland, Øyvind Storesund; Maradudin, Alexei A.; Nordam, Tor; Letnes, Paul Anton; Simonsen, Ingve (Journal article; Peer reviewed, 2017)The transmission of polarized light through a two-dimensional randomly rough interface between two dielectric media has been much less studied, by any approach, than the reflection of light from such an interface. We have ... -
Optical Polarization Effects of Rough and Structured Surfaces
Letnes, Paul Anton (Doktoravhandlinger ved NTNU, 1503-8181; 2012:234, Doctoral thesis, 2012)The reflection and scattering of light from surfaces is a topic that has been much discussed in the scientific literature. The application of optical methods for the characterization of surfaces and the understanding of ... -
Satellite peaks in the scattering of light from the two-dimensional randomly rough surface of a dielectric film on a planar metal surface
Nordam, Tor; Letnes, Paul Anton; Simonsen, Ingve; Maradudin, Alexei A. (Journal article; Peer reviewed, 2012)A nonperturbative, purely numerical, solution of the reduced Rayleigh equation for the scattering of p- and s-polarized light from a dielectric film with a two-dimensional randomly rough surface deposited on a planar ...
