This paper presents the application of several optical measurement techniques for the characterization of the combustion behavior of the pilot burner of a gas turbine combustor developed according to the lean premixed prevaporized concept The vaporization of the kerosene fuel (Jet-A) injected by a pilot spray and its consequent mixing with air has been visualized using combined laser-induced fluorescence and Mie scattering measurements. The laser-induced fluorescence/Mie measurements can be used to estimate the length and time scales for evaporation and mixing with air of kerosene (Jet-A) for the lean; premixed; and prevaporized pilot burner. In addition; the feasibility of using laser-induced incandescence for soot characterization has been investigated. Finally; spontaneous flame emission (i.e; chemiluminescence and thermal radiation) have been measured providing information on the overall characteristics of the combustion;
