1. The spectral reflectance of coniferous tree stands and of barley influenced by stress : an analysis of field measured spectral data
Abstract : This thesis focuses on the spectral signatures for vegetation. Knowledge about the spectral characteristics of different vegetation types is imperative for an efficient use of existing remote sensing systems, and also to provide guidelines for sensor development. READ MORE

2. Quantitative diffuse reflectance spectroscopy : myocardial oxygen transport from vessel to mitochondria
Abstract : In the field of biomedical optics, diffuse reflectance spectroscopy (DRS) is a frequently used technique for obtaining information about the optical properties of the medium under investigation. The method utilizes spectral difference between incident and backscattered light intensity for quantifying the underlying absorption and scattering processes that affects the light-medium interaction.

3. Remote sensing of grassland communities : integrated effects of soil nutrients and habitat age
Abstract : Semi-natural grasslands are characterized by high fine-scale plant species richness. The richest grassland communities, with many habitat-specialist species, are found in ancient grassland sites that have a long continuity of grazing management and low levels of soil nutrients. Grazed grasslands were widespread in the historical landscape. READ MORE

4. Appearance characterisation of textured polymeric surfaces
Abstract : Appearance demands for industrial products are generally increasing since they are closely related to the overall quality impression. Consequently, there is a need to define appearance through its main descriptors, which are gloss, colour and surface texture, as well as the relations between them. READ MORE

5. Multispectral reflectance measurements and signature analysis
Abstract : The use of aerial photographs and satellite images may be.facilitated by a deeper knowledge of the reflection properties of natural features. This thesis, which includes a concluding essay and three more papers, is a study of two methods of multispectral reflectance measurements. READ MORE
