For the understanding of soot formation in combustion processes comprehensive information about local size properties of complex soot aggregates is desired. Elastic light scattering (ELS) is a well-established optical technique which allows for the in situ determination of aggregate size and fractal dimension of soot particles in flames [1]. Reimann et al. [2] used a two-dimensional combination of ELS and laser-induced incandescence (LII) for the determination of various parameters of soot particles in a premixed flame from a porous flat flame burner (McKenna type). Although the general approach was successful both the measuring range in terms of aggregate size and the information obtained were limited because of the use of a fixed scattering angle of 90°.
