- Abstract
- The work presented in this thesis is an experimental study on the applicability of low power lasers to Rayleigh scattering thermometry. An optical set up involving a 15 mw He-Ne laser and a data acquisition system were used to measure scattered radiation from a premixed laminar methane-air flame. Temperature traverse profiles were extracted from scttered signals from transverse measurements at different axial locations in the flame.
