  1. 1. In Vivo Diffuse Reflectance Spectroscopy of Human Tissue : From Point Measurements to Imaging

    Författare :Erik Häggblad; Göran Salerud; Tomas Strömberg; Maurice C. G. Maurice C. G. Aalders; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical engineering; Medicinsk teknik;

    Sammanfattning : This thesis presents the non-invasive use of diffuse reflectance spectroscopy (DRS) to provide information about the biochemical composition of living tissue. During DRS measurements, the incident, visible light is partially absorbed by chromophores but also scattered in the tissue before being remitted. LÄS MER

  3. 2. Infrared Emittance of Paper : Method Development, Measurements and Application

    Författare :Caroline Hyll; Lars Mattsson; Hannes Vomhoff; Carl-Gustaf Ribbing; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emittance; Emissivity; Thermography; Paper; Sheet; Papermaking; Paper mechanics; Moisture; Material properties; Reflectance; Transmittance; Absorptance; Infrared; Mid-wavelength infrared; MWIR; Long-wavelength infrared; LWIR; Angle-resolved; Directional;

    Sammanfattning : Thermography is a non-destructive technique which uses infrared radiation to obtain the temperature distribution of an object. The technique is increasingly used in the pulp and paper industry. To convert the detected infrared radiation to a temperature, the emittance of the material must be known. LÄS MER

  5. 4. Multispectral reflectance measurements and signature analysis

    Författare :Wolter Arnberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER
