Abstract
The invention relates to a process for measuring particle size by measuring the attenuation of radiation after its passage through a defined measuring section containing a disperse system. According to the invention the temporally fluctuating transmission signal is recorded with variable time or spatial resolution. The transmission signals recorded then undergo a non-linear operation. The result of that non-linear operation is represented and analyzed as a spectral curve, i.e., as a function of the spatial or temporal resolution.
