   Abstract : Transparent wood (TW) shows interesting optical properties and offers a sustainable alternative to petroleum-based polymer glasses. The influence of the TW internal structure (e.g. READ MORE

4. 2. Development of Laser-Spectroscopic Techniques for New Detection Schemes in Combustion Diagnostics

   Author : Johan Zetterberg; Förbränningsfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Laser-Spectroscopy; Laser Combustion Diagnostics; Rayleigh scattering; FRS; LIF; Polarization Spectroscopy; PS; IRPS;

   Abstract : The thesis work, aimed at the development of laser-spectroscopic detection schemes, consists of three parts, concerned with the development and application of different techniques. The development of UV filtered Rayleigh scattering (FRS) for thermometry and fuel/air ratio measurements, using a frequency tripled, single-longitudinal-mode alexandrite laser at ~254 nm together with an isotopically enhanced mercury filter, is examined first.
