“…While in some applications it is sufficient to model the polydisperse aerosol as monodisperse and interpret the recovered aggregate morphology as some average representation of the aggregates (e.g. [10,13,15]), this approach is highly approximate since the recovered aggregate size is not the arithmetic mean of the size distribution but rather the ratio of higher moments [9,16]. Moreover, it is becoming increasingly important to obtain more detailed information about the distribution of aggregate sizes; for example, emission regulations for combustion technologies are size specific, in recognition that the impact of soot aggregates on human health is strongly dependent on aggregate size [17].…”

“…Recent innovations in experimental apparatus [10,11,13] have led to the possibility of obtaining a much larger set of angular measurements, which in principle can be used to relax the need to assume a distribution shape. In a previous work [11], we demonstrated that P(N p ) can be estimated by solving a matrix analogue of Eq.…”

“…13 This method has a good spatial resolution, typically limited by the laser beam diameter, which allows the detection of soot concentration in different regions of the system. Methods based on light extinction 6,9 and light scattering 14 can also be used with similar performance. However, these three techniques require a set of signal treatments and a previous knowledge of the size particles which difficult the use of them as a real-time probe due to its low temporal resolution.…”
