  1. 1. Lifetime Surface Phosphor Thermometry - Technique Developments, Sources of Error, and Applications

    Författare :Henrik Feuk; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; phosphor thermometry; thermographic phosphors; decay time; lifetime; laser-induced phosphorescence; thermometry; high temperature; surface thermometry; maximum entropy method; Kubelka-Munk; Fysicumarkivet A:2023:Feuk;

    Sammanfattning : Temperature is not only a fundamental aspect of everyday life, but it is also an essential metric for thermal conversion systems concerning efficiency, emissions, and component lifetime estimation. Therefore, a vast range of different methods to measure temperature has been developed. LÄS MER
