  1. 1. 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

  3. 2. Detection and Tracking in Thermal Infrared Imagery

    Författare :Amanda Berg; Michael Felsberg; Jörgen Ahlberg; Thomas B. Moeslund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; thermal; infrared; detection; tracking;

    Sammanfattning : Thermal cameras have historically been of interest mainly for military applications. Increasing image quality and resolution combined with decreasing price and size during recent years have, however, opened up new application areas. They are now widely used for civilian applications, e.g. LÄS MER

  4. 3. III-V Nanowire-based Infrared Photodetectors : Design, Fabrication and Characterization

    Författare :Vishal Jain; Fasta tillståndets fysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanowire; infrared; photodetector; APD; thermal imaging; telecommunication; fabrication; InP; InAsP; Fysicumarkivet A:2016:Jain;

    Sammanfattning : Semiconductors are the backbone of almost every electrical or optical component, one of them being photodetectors. Photodetectors are used in many applications such as digital cameras or solar panels. They can also be designed to detect the omnipresent infrared radiation, discovered in 1800, which is invisible to human eye. LÄS MER

    Författare :Christopher Robin Samuelsson; Jesper Haglund; Maja Elmgren; Bor Gregorcic; Paula R. L. Heron; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inquiry-based; inquiry; infrared cameras; laboratory education; active engagement; systematic engagement; thermodynamics; phase transitions; calorimetry; curiosity; conceptual change; resources framework; social semiotics; physics education research; metacognition; laboratory skills; exemplars; instant inquiry; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : This thesis focuses on students’ engagement in inquiry-based laboratory learning environments. The aim of the research is to explore what it is that makes students active and systematic in these types of lab learning environments. LÄS MER

  7. 5. Surface Status Classification, Utilizing Image Sensor Technology and Computer Models

    Författare :Patrik Jonsson; Hans-Erik Nilsson; Benny Thörnberg; Jörgen Bogren; Torbjörn Eltoft; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; road condition; NIR; infrared; remote sensing; signal processing; classifiers;

    Sammanfattning : There is a great need to develop systems that can continuously provide correct information about road surface status depending on the prevailing weather conditions. This will minimize accidents and optimize transportation. LÄS MER
